1c6c51d137 [GSB] Cope with elided conformance requirements in concrete nested types. 
If we encounter an associated type reference within a concrete type, but
haven't seen a specific protocol requirement, add the protocol
conformance.

Fixes rdar://problem/33139928 and another crasher.

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) {

a28ef70cd3 [swiftc (40 vs. 5572)] Add crasher in swift::SILModule::getOrCreateFunction 
Add test case for crash triggered in `swift::SILModule::getOrCreateFunction`.

Current number of unresolved compiler crashers: 40 (5572 resolved)

/cc @swiftix - just wanted to let you know that this crasher caused an assertion failure for the assertion `fn->getLoweredFunctionType() == constantType` added on 2015-04-07 by you in commit 0c2fc7c1 :-)

Assertion failure in [`lib/SIL/SILModule.cpp (line 293)`](a8b5a4a18a/lib/SIL/SILModule.cpp (L293)):

```
Assertion `fn->getLoweredFunctionType() == constantType' failed.

When executing: swift::SILFunction *swift::SILModule::getOrCreateFunction(swift::SILLocation, swift::SILDeclRef, swift::ForDefinition_t)
```

Assertion context:

```c++
  auto name = constant.mangle();
  auto constantType = Types.getConstantType(constant).castTo<SILFunctionType>();
  SILLinkage linkage = constant.getLinkage(forDefinition);

  if (auto fn = lookUpFunction(name)) {
    assert(fn->getLoweredFunctionType() == constantType);
    assert(fn->getLinkage() == linkage ||

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.

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.

0b0f032d8f [swiftc (32 vs. 5563)] Add crasher in swift::GenericSignatureBuilder::addSameTypeRequirementToConcrete 
Add test case for crash triggered in `swift::GenericSignatureBuilder::addSameTypeRequirementToConcrete`.

Current number of unresolved compiler crashers: 32 (5563 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `conformance->isConcrete() || Concrete->isExistentialType()` added on 2017-02-23 by you in commit cbbf4154 :-)

Assertion failure in [`lib/AST/GenericSignatureBuilder.cpp (line 3371)`](c21699b4e5/lib/AST/GenericSignatureBuilder.cpp (L3371)):

```
Assertion `conformance->isConcrete() || Concrete->isExistentialType()' failed.

When executing: ConstraintResult swift::GenericSignatureBuilder::addSameTypeRequirementToConcrete(swift::GenericSignatureBuilder::PotentialArchetype *, swift::Type, const swift::GenericSignatureBuilder::RequirementSource *)
```

Assertion context:

```c++
    }

    conformances.insert({protocol, *conformance});

    // Abstract conformances are acceptable for existential types.
    assert(conformance->isConcrete() || Concrete->isExistentialType());

    // Update the requirement source now that we know it's concrete.
    // FIXME: Bad concrete source info.
    auto concreteSource = Source->viaConcrete(*this,
                                              conformance->isConcrete()

Add test case for crash triggered in `swift::TypeChecker::validateDecl(...)`.

Current number of unresolved compiler crashers: 26 (5563 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `hasInterfaceType() && "No interface type was set"` added on 2016-12-04 by you in commit c1a21613 :-)

Assertion failure in [`lib/AST/Decl.cpp (line 1813)`](1a9ccd347c/lib/AST/Decl.cpp (L1813)):

```
Assertion `hasInterfaceType() && "No interface type was set"' failed.

  return !TypeAndAccess.getPointer().isNull();
}

Type ValueDecl::getInterfaceType() const {
  assert(hasInterfaceType() && "No interface type was set");
  return TypeAndAccess.getPointer();
}

244098d61c [swiftc (22 vs. 5563)] Add crasher in swift::ProtocolDecl::requiresClassSlow(...) 
Add test case for crash triggered in `swift::ProtocolDecl::requiresClassSlow(...)`.

Current number of unresolved compiler crashers: 22 (5563 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `type && "Should have type checked inheritance clause by now"` added on 2017-04-28 by you in commit 0d4a0b7d :-)

Assertion failure in [`lib/AST/Decl.cpp (line 2989)`](c9b59ed644/lib/AST/Decl.cpp (L2989)):

```
Assertion `type && "Should have type checked inheritance clause by now"' failed.

When executing: bool swift::ProtocolDecl::requiresClassSlow()
```

Assertion context:

```c++

  // Otherwise, check if the inheritance clause contains a
  // class-constrained existential.
  //
  // FIXME: Use the requirement signature if available.
  ProtocolDeclBits.RequiresClass = false;
  for (auto inherited : getInherited()) {
    auto type = inherited.getType();
    assert(type && "Should have type checked inheritance clause by now");
    if (type->isExistentialType()) {
      auto layout = type->getExistentialLayout();
