9d1e076aa1 [swiftc (53 vs. 5582)] Add crasher in swift::Substitution::Substitution 
Add test case for crash triggered in `swift::Substitution::Substitution`.

Current number of unresolved compiler crashers: 53 (5582 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `Replacement->isMaterializable() && "cannot substitute with a non-materializable type"` added on 2016-09-08 by you in commit 9cba638c :-)

Assertion failure in [`lib/AST/Substitution.cpp (line 43)`](9c9db59c97/lib/AST/Substitution.cpp (L43)):

```
Assertion `Replacement->isMaterializable() && "cannot substitute with a non-materializable type"' failed.

When executing: swift::Substitution::Substitution(swift::Type, ArrayRef<swift::ProtocolConformanceRef>)
```

Assertion context:

```c++
                           ArrayRef<ProtocolConformanceRef> Conformance)
  : Replacement(Replacement), Conformance(Conformance)
{
  // The replacement type must be materializable.
  assert(Replacement->isMaterializable()
         && "cannot substitute with a non-materializable type");
}

bool Substitution::isCanonical() const {
  if (!getReplacement()->isCanonical())
    return false;
```

bda127ae2a [swiftc (47 vs. 5582)] Add crasher in swift::constraints::ConstraintGraph::addConstraint(...) 
Add test case for crash triggered in `swift::constraints::ConstraintGraph::addConstraint(...)`.

Current number of unresolved compiler crashers: 47 (5582 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index"` added on 2013-12-09 by you in commit 11794095 :-)

Assertion failure in [`lib/Sema/ConstraintGraph.cpp (line 50)`](725702c283/lib/Sema/ConstraintGraph.cpp (L50)):

```
Assertion `impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index"' failed.

When executing: std::pair<ConstraintGraphNode &, unsigned int> swift::constraints::ConstraintGraph::lookupNode(swift::TypeVariableType *)
```

Assertion context:

```c++
std::pair<ConstraintGraphNode &, unsigned>
ConstraintGraph::lookupNode(TypeVariableType *typeVar) {
  // Check whether we've already created a node for this type variable.
  auto &impl = typeVar->getImpl();
  if (auto nodePtr = impl.getGraphNode()) {
    assert(impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index");
    assert(TypeVariables[impl.getGraphIndex()] == typeVar &&
           "Type variable mismatch");
    return { *nodePtr, impl.getGraphIndex() };
  }

```

fd560b7cb3 [swiftc (45 vs. 5582)] Add crasher in swift::TypeChecker::resolveIdentifierType 
Add test case for crash triggered in `swift::TypeChecker::resolveIdentifierType`.

Current number of unresolved compiler crashers: 45 (5582 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!isa<ProtocolDecl>(nominal) && "Cannot be a protocol"` added on 2017-04-23 by you in commit 07c189558 :-)

Assertion failure in [`lib/Sema/TypeCheckType.cpp (line 688)`](bd02831599/lib/Sema/TypeCheckType.cpp (L688)):

```
Assertion `!isa<ProtocolDecl>(nominal) && "Cannot be a protocol"' failed.

When executing: swift::Type diagnoseUnknownType(swift::TypeChecker &, swift::DeclContext *, swift::Type, swift::SourceRange, swift::ComponentIdentTypeRepr *, TypeResolutionOptions, NameLookupOptions, swift::GenericTypeResolver *, UnsatisfiedDependency *)
```

Assertion context:

```c++
          (nominal = nominalDC->getAsNominalTypeOrNominalTypeExtensionContext())) {
        // Attempt to refer to 'Self' within a non-protocol nominal
        // type. Fix this by replacing 'Self' with the nominal type name.

        // Retrieve the nominal type and resolve it within this context.
        assert(!isa<ProtocolDecl>(nominal) && "Cannot be a protocol");
        auto type = resolver->mapTypeIntoContext(
          dc->getInnermostTypeContext()->getSelfInterfaceType());
        if (type->hasError())
          return type;

ee68ff4170 Sema: Use foundDC in resolveTypeInContext() 
Now that we remember the DeclContext of lookup results when
doing unqualified lookup, we don't have to walk parent contexts
again to find this DeclContext.

This means that unqualified lookup is now the "single source of
truth" for what names are visible and why.

a39b5eb53b Sema: Move preCheckExpression() out of solveForExpression() 
There are two "RAII cleaners" here:

- CleanupIllFormedExpressionRAII cleans up the Expr in its final state
- ExprCleanser walks the Expr before it is mutated and collects
  sub-expressions, then cleans those up after

The subtle difference comes into play if we started to apply the
solution (which can fail, leaving the AST in an inconsistent state)
or if preCheckExpression() modified the AST.

The latter case was causing an ASan failure because we were not
cleaning up type variables in new nodes introduced by
preCheckExpression().

Fix this by moving the preCheckExpression() call out of
solveForExpression(), so that if solveForExpression() is called
with TypeCheckExprFlags::SkipApplyingSolution, we don't mutate the
AST at all.

Sigh...

138b0361d2 [Type checker] Don't allow type variables to bind to dependent members. 
When a type variable binds to an (unresolved) dependent member type,
it prevents us from inferring the type variable and adds no useful
information to the system. Refuse to bind type variables to dependent
member types.

8b3b3e4639 [swiftc (47 vs. 5577)] Add crasher in swift::ASTVisitor 
Add test case for crash triggered in `swift::ASTVisitor`.

Current number of unresolved compiler crashers: 47 (5577 resolved)

/cc @rudkx - just wanted to let you know that this crasher caused an assertion failure for the assertion `hasType(E) && "Expected type to have been set!"` added on 2016-12-11 by you in commit 1139f872 :-)

Assertion failure in [`lib/Sema/ConstraintSystem.h (line 1544)`](1a0aa2f332/lib/Sema/ConstraintSystem.h (L1544)):

```
Assertion `hasType(E) && "Expected type to have been set!"' failed.

When executing: swift::Type swift::constraints::ConstraintSystem::getType(const swift::Expr *) const
```

Assertion context:

```c++
    return ExprTypes.find(E) != ExprTypes.end();
  }

  /// Get the type for an expression.
  Type getType(const Expr *E) const {
    assert(hasType(E) && "Expected type to have been set!");
    // FIXME: lvalue differences
    //    assert((!E->getType() ||
    //            E->getType()->isEqual(ExprTypes.find(E)->second)) &&
    //           "Mismatched types!");
    return ExprTypes.find(E)->second;
```

bad6c2eb2f [swiftc (43 vs. 5577)] Add crasher in swift::lookupVisibleMemberDecls 
Add test case for crash triggered in `swift::lookupVisibleMemberDecls`.

Current number of unresolved compiler crashers: 43 (5577 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!BaseTy->hasUnboundGenericType()` added on 2017-03-20 by you in commit 573e832f :-)

Assertion failure in [`lib/AST/LookupVisibleDecls.cpp (line 784)`](f0d485c833/lib/AST/LookupVisibleDecls.cpp (L784)):

```
Assertion `!BaseTy->hasUnboundGenericType()' failed.

When executing: virtual void (anonymous namespace)::OverrideFilteringConsumer::foundDecl(swift::ValueDecl *, swift::DeclVisibilityKind)
```

Assertion context:

```c++

    // Does it make sense to substitute types?

    // Don't pass UnboundGenericType here. If you see this assertion
    // being hit, fix the caller, don't remove it.
    assert(!BaseTy->hasUnboundGenericType());

    // If the base type is AnyObject, we might be doing a dynamic
    // lookup, so the base type won't match the type of the member's
    // context type.
    //
```

158c048149 [Type checker] Always compute protocol requirement signature first. 
The protocol requirement signature is key to conformance access paths
and other queries related to protocols. Make sure we create it first.

be5bc3fd07 [GSB] Eliminate two more uses of ArchetypeResolutionKind::AlwaysPartial. 
We don't need to force the creation of potential archetypes when
finding anchors, because new potential archetypes will only be created
by this process in ill-formed generic signatures. Tolerate failure
whenever this happens (for now) and the failure paths will become dead
once AlwaysPartial is eliminated fully.

15214402df [swiftc (43 vs. 5572)] Add crasher in swift::Mangle::Mangler::appendIdentifier(...) 
Add test case for crash triggered in `swift::Mangle::Mangler::appendIdentifier(...)`.

Current number of unresolved compiler crashers: 43 (5572 resolved)

/cc @eeckstein - just wanted to let you know that this crasher caused an assertion failure for the assertion `!isDigit(ident[Pos]) && "first char of sub-string may not be a digit"` added on 2016-12-02 by you in commit 684092d7 :-)

Assertion failure in [`include/swift/Demangling/ManglingUtils.h (line 195)`](a45d7e3d2a/include/swift/Demangling/ManglingUtils.h (L195)):

```
Assertion `!isDigit(ident[Pos]) && "first char of sub-string may not be a digit"' failed.

When executing: void swift::Mangle::mangleIdentifier(Mangler &, llvm::StringRef) [Mangler = swift::Mangle::Mangler]
```

Assertion context:

```c++
      // Mangle the sub-string up to the next word substitution (or to the end
      // of the identifier - that's why we added the dummy-word).
      // The first thing: we add the encoded sub-string length.
      M.Buffer << (Repl.StringPos - Pos);
      assert(!isDigit(ident[Pos]) &&
             "first char of sub-string may not be a digit");
      do {
        // Update the start position of new added words, so that they refer to
        // the begin of the whole mangled Buffer.
        if (WordsInBuffer < M.Words.size() &&
            M.Words[WordsInBuffer].start == Pos) {
```

Add test case for crash triggered in `swift::GenericSignatureBuilder::PotentialArchetype::updateNestedTypeForConformance`.

Current number of unresolved compiler crashers: 41 (5572 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `parentEquiv->conformsTo.count(proto) > 0 && "No conformance requirement"` added on 2017-06-06 by you in commit 52e52b56 :-)

Assertion failure in [`lib/AST/GenericSignatureBuilder.cpp (line 1750)`](f248c3c83e/lib/AST/GenericSignatureBuilder.cpp (L1750)):

```
Assertion `parentEquiv->conformsTo.count(proto) > 0 && "No conformance requirement"' failed.

When executing: void concretizeNestedTypeFromConcreteParent(GenericSignatureBuilder::PotentialArchetype *, GenericSignatureBuilder::PotentialArchetype *, swift::GenericSignatureBuilder &)
```

Assertion context:

```c++
  auto assocType = nestedPA->getResolvedAssociatedType();
  if (!assocType) return;

  auto proto = assocType->getProtocol();
  assert(parentEquiv->conformsTo.count(proto) > 0 &&

a72a2bf730 [GSB] Avoid recursively growing increasingly-nested potential archetypes. 
In some circumstances, we could end up growing increasingly-nested
potential archetypes due to a poor choice of representatives and
anchors. Address this in two places:

* Always prefer to use the potential archetype with a lower nesting
  depth (== number of nested types) to one with a greater nesting
  depth, so we don't accumulate more nested types onto the
  already-longer potential archetypes, and

* Prefer archetype anchors with a lower nesting depth *except* that we
  always prefer archetype anchors comprised of a sequence of
  associated types (i.e., no concrete type declarations), which is
  important for canonicalization.

Fixes SR-4757 / rdar://problem/31912838, as well as a regression
involving infinitely-recursive potential archetypes caused by the
previous commit.

Doug Gregor
52e52b564b [GSB] Improve handling of conformances resolved by concrete types. 
Centralize and simplify the handling of conformance requirements
resolved by same-type-to-concrete requirements in a few ways:

* Always store a ProtocolConformanceRef in via-superclass and
  via-concrete requirement sources, so we never lose this information.

* When concretizing a nested type based on its parent, use the
  via-concrete conformance information rather than performing lookup
  again, simplifying this operation considerably and avoiding
  redundant lookups.

* When adding a conformance requirement to a potential archetype that
  is equivalent to a concrete type, attempt to find and record the
  conformance.

Fixes SR-4295 / rdar://problem/31372308.
