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.

c45073efd1 [QoI] Don't try to lookup members on incorrect type while diagnosing keypath components 
While trying to diagnose problems related to keypath components
don't assume that type of the component is always correct, check
before trying to see if it's bridged type or has members.

88556eec94 Avoid building conformance lookup tables when we don't have to. 
- Deinitializers never get a custom Objective-C name.
- Classes and protocols are never bridged themselves; that only matters
  for structs and enums.

This avoids another circularity issue like the one in a8bc132565,
where the Clang importer ends up importing a class and hands it to the
type checker, which then asks about conformances. The conformance
lookup table goes to add the extension from the Swift module, except
that the Swift module is what asked for the import in the first place.

It's possible there's a more general solution here, but this
particular change is good even in the non-crashy cases, and definitely
safe for Swift 4.0. Even if the test case is even more idiosyncratic
than the last one.

The test case change for SourceKit is probably due to the first
category not triggering the import of the other two
categories. Changes in import order have been known to affect source
compatibility, though not frequently. However, categories are not
intended to be ordered in the first place. There's still more we can
do in this space, and implicitly depending on these calls /outside/ of
the importer to control category import order was quite brittle
anyway.

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.
    //
```

ac8e8aa1b3 [GSB] Stop creating unresolved potential archetypes; rework typo correction. 
The small-but-significant change to the generic signature builder is
to refuse to create unresolved potential archetypes. Instead, delay
any requirement that depends on such type, to be reprocessed once
we've seen all of the other requirements. If the type can be resolved
later, it will be; Otherwise, the type checker will complain when it
sees an unresolvable type. By itself, this fixes the crash in SR-2796.

Doing this by itself regresses diagnostics because typo correction in
the generic signature builder no longer kicks in. Therefore, implement
typo correction for these cases in the type checker proper, using its
existing facilities for typo correction. The result is more consistent
code with a better result.

Fixes SR-2796 / rdar://problem/28544316.

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) {
```

9388417131 [swiftc (41 vs. 5572)] Add crasher in swift::GenericSignatureBuilder::PotentialArchetype::updateNestedTypeForConformance 
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 &&

6244245b28 [swiftc (40 vs. 5569)] Add crasher in swift::GenericSignatureBuilder::addTypeRequirement 
Add test case for crash triggered in `swift::GenericSignatureBuilder::addTypeRequirement`.

Current number of unresolved compiler crashers: 40 (5569 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `constraintType && "Missing constraint type?"` added on 2017-04-07 by you in commit c522bb52 :-)

Assertion failure in [`lib/AST/GenericSignatureBuilder.cpp (line 3110)`](4d33756923/lib/AST/GenericSignatureBuilder.cpp (L3110)):

```
Assertion `constraintType && "Missing constraint type?"' failed.

When executing: ConstraintResult swift::GenericSignatureBuilder::addTypeRequirement(UnresolvedType, UnresolvedType, swift::GenericSignatureBuilder::FloatingRequirementSource, swift::GenericSignatureBuilder::UnresolvedHandlingKind)
```

Assertion context:

```c++
