04a9714d9b [Type checker] Short-circuit uses of concrete typealiases in protocols. 
Hack to allow IndexDistance to become a deprecated typealias. The actual
fix here involves deeper surgery into the substitution machinery.

b6200728a6 Sema: Fix crash on invalid openUnboundGenericType() 
We can't construct a nominal type with an ErrorType as a
parent, so in the bad circular case, return a Type() instead
to bail out of transform() altogether.

0d9745f6eb libSyntax: teach parser to parse dictionary and array literals. (#12821) 
This commit also adds ArrayExpr and DictionaryExpr to the libSyntax nodes
family. Also, it refactors the original parser code for these two
expressions to better fit to the design of SyntaxParsingContext.

This commit has also fixed two crashers.

fe54e70fce [GSB] Don't infer requirements from types in the definitions of protocols. 
Previously, we were inferring requirements from types within the definitions
of protocols, e.g., given something like:

    protocol P {
      associatedtype A: Collection
      associatedtype B where A.Element == Set<B>
    }

we would infer that B: Hashable. The code for doing this was actually
incorrect due to its mis-use of requirement sources, causing a few
crashers. Plus, it's not a good idea in general because it hides the
actual requirements on B. Stop doing this.

Also stop trying to infer requirements from conditional
requirements---those have already been canonicalized and minimized, so
there's nothing to infer from.

832a154b08 [GSB] Make sure we wire up same-named type declarations consistently. 
Fixes a former crasher that included well-formed code that was rejected
by my previous refactoring. Said crasher now passes, and IRGen's properly
as well. Also, account for three more fixed crashers.

abc88eff1d [swiftc (70 vs. 5600)] Add crasher in swift::ASTContext::getConformance 
Add test case for crash triggered in `swift::ASTContext::getConformance`.

Current number of unresolved compiler crashers: 70 (5600 resolved)

/cc @huonw - just wanted to let you know that this crasher caused an assertion failure for the assertion `(bool)typeSig == (bool)extensionSig && "unexpected generic-ness mismatch on conformance"` added on 2017-09-14 by you in commit 945f723d :-)

Assertion failure in [`lib/AST/ProtocolConformance.cpp (line 320)`](01416ab5bf/lib/AST/ProtocolConformance.cpp (L320)):

```
Assertion `(bool)typeSig == (bool)extensionSig && "unexpected generic-ness mismatch on conformance"' failed.

When executing: void swift::NormalProtocolConformance::differenceAndStoreConditionalRequirements()
```

Assertion context:

```c++

  auto extensionSig = DC->getGenericSignatureOfContext();

  // If the type is generic, the extension should be too, and vice versa.
  assert((bool)typeSig == (bool)extensionSig &&
         "unexpected generic-ness mismatch on conformance");
  if (!typeSig)
    return;

b5ca50619f [swiftc (67 vs. 5600)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 67 (5600 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth && "parameter hasn't been validated"` added on 2017-02-22 by you in commit fdb0a186 :-)

Assertion failure in [`lib/AST/Type.cpp (line 1107)`](ab72b541f9/lib/AST/Type.cpp (L1107)):

```
Assertion `gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth && "parameter hasn't been validated"' failed.

When executing: swift::CanType swift::TypeBase::getCanonicalType()
```

Assertion context:

```c++

  case TypeKind::GenericTypeParam: {
    GenericTypeParamType *gp = cast<GenericTypeParamType>(this);
    auto gpDecl = gp->getDecl();
    assert(gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth &&
           "parameter hasn't been validated");
    Result = GenericTypeParamType::get(gpDecl->getDepth(), gpDecl->getIndex(),
                                       gpDecl->getASTContext());
    break;
  }

```

4f27b78562 [swiftc (66 vs. 5600)] Add crasher in swift::TypeChecker::resolveTypeWitness 
Add test case for crash triggered in `swift::TypeChecker::resolveTypeWitness`.

Current number of unresolved compiler crashers: 66 (5600 resolved)

/cc @jtbandes - just wanted to let you know that this crasher caused an assertion failure for the assertion `(!isComplete() || isInvalid()) && "Conformance already complete?"` added on 2016-01-07 by you in commit 8cc8c5cc :-)

Assertion failure in [`lib/AST/ProtocolConformance.cpp (line 542)`](9ec6587ec3/lib/AST/ProtocolConformance.cpp (L542)):

```
Assertion `(!isComplete() || isInvalid()) && "Conformance already complete?"' failed.

When executing: void swift::NormalProtocolConformance::setTypeWitness(swift::AssociatedTypeDecl *, swift::Type, swift::TypeDecl *) const
```

Assertion context:

Add test case for crash triggered in `swift::ProtocolConformance::getTypeWitnessAndDecl`.

Current number of unresolved compiler crashers: 60 (5600 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `known != TypeWitnesses.end() && "Didn't resolve witness?"` added on 2017-05-03 by you in commit dbb973aa :-)

Assertion failure in [`lib/AST/ProtocolConformance.cpp (line 474)`](488aa70600/lib/AST/ProtocolConformance.cpp (L474)):

ea1396c364 [GSB] Only build potential archetypes for associated type "anchors". 
Use the "override" information in associated type declarations to provide
AST-level access to the associated type "anchor", i.e., the canonical
associated type that will be used in generic signatures, mangling,
etc.

In the Generic Signature Builder, only build potential archetypes for
associated types that are anchors, which reduces the number of
potential archetypes we build when type-checking the standard library
by 14% and type-checking time for the standard library by 16%.

There's a minor regression here in some generic signatures that were
accidentally getting (correct) same-type constraints. There were
existing bugs in this area already (Huon found some of them), while
will be addressed as a follow-up.

Fies SR-5726, where we were failing to type-check due to missed
associated type constraints.

4a0df93769 [swiftc (57 vs. 5600)] Add crasher in swift::GenericSignature::getConformanceAccessPath 
Add test case for crash triggered in `swift::GenericSignature::getConformanceAccessPath`.

Current number of unresolved compiler crashers: 57 (5600 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `hasConformanceInSignature(inProtocol->getRequirementSignature(), subjectType, conformingProto) && "missing explicit conformance in requirement signature"` added on 2017-03-08 by you in commit 1f8b0f9b :-)

Assertion failure in [`lib/AST/GenericSignature.cpp (line 854)`](38bf97bacb/lib/AST/GenericSignature.cpp (L854)):

```
Assertion `hasConformanceInSignature(inProtocol->getRequirementSignature(), subjectType, conformingProto) && "missing explicit conformance in requirement signature"' failed.

When executing: auto swift::GenericSignature::getConformanceAccessPath(swift::Type, swift::ProtocolDecl *, swift::ModuleDecl &)::(anonymous class)::operator()(ArrayRef<swift::Requirement>, const RequirementSource *, swift::ProtocolDecl *, swift::Type, swift::ProtocolDecl *) const
```

Assertion context:

```c++
          ->getCanonicalTypeInContext(subjectType,
                                      *inProtocol->getParentModule());

        assert(hasConformanceInSignature(inProtocol->getRequirementSignature(),
                                         subjectType, conformingProto) &&
               "missing explicit conformance in requirement signature");

        // Record this step.
        path.path.push_back({subjectType, conformingProto});
        return;

797df6e8d7 Eliminate the _*Indexable protocols. 
The various _*Indexable protocols only exist to work around the lack of
recursive protocol constraints. Eliminate all of the *_Indexable protocols,
collapsing their requirements into the corresponding Collection protocol
(e.g., _MutableIndexable —> Collection).

This introduces a number of extraneous requirements into the various
Collection protocols to work around bugs in associated type
inference. Specifically, to work around the lack of "global" inference
of associated type witnesses. These hacks were implicitly present in
the *Indexable protocols; I've made marked them as ABI FIXMEs here so
we can remove them when associated type inference improves.

Fixes rdar://problem/21935030 and a number of ABI FIXMEs in the library.

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `isCanonicalTypeInContext(result, builder)` added on 2017-02-02 by you in commit ded7e83a :-)

Assertion failure in [`lib/AST/GenericSignature.cpp (line 713)`](d98d7c4fe5/lib/AST/GenericSignature.cpp (L713)):

```
Assertion `isCanonicalTypeInContext(result, builder)' failed.

Assertion context:

```c++

  auto result = type->getCanonicalType();

  assert(isCanonicalTypeInContext(result, builder));
  return result;
}

d32b32f3e2 [swiftc (58 vs. 5595)] Add crasher in swift::constraints::ConstraintSystem::getTypeOfMemberReference 
Add test case for crash triggered in `swift::constraints::ConstraintSystem::getTypeOfMemberReference`.

Current number of unresolved compiler crashers: 58 (5595 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!type->hasUnboundGenericType()` added on 2017-05-21 by you in commit fe419008 :-)

Assertion failure in [`lib/Sema/ConstraintSystem.cpp (line 472)`](64f6b561b5/lib/Sema/ConstraintSystem.cpp (L472)):

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

When executing: swift::Type swift::constraints::ConstraintSystem::openType(swift::Type, OpenedTypeMap &)
```

Assertion context:

```c++
      return type;
    });
}

Type ConstraintSystem::openType(Type type, OpenedTypeMap &replacements) {
  assert(!type->hasUnboundGenericType());

  if (!type->hasTypeParameter())
    return type;

  return type.transform([&](Type type) -> Type {
```

d93bed5ed1 [GSB] Move a well-formed GenericSignatureBuilder to be the canonical builder. 
Once we compute a generic signature from a generic signature builder,
all queries involving that generic signature will go through a separate
(canonicalized) builder, and the original builder can no longer be used.
The canonicalization process then creates a new, effectively identical
generic signature builder. How silly.

Once we’ve computed the signature of a generic signature builder, “register”
it with the ASTContext, allowing us to move the existing generic signature
builder into place as the canonical generic signature builder. The builder
requires minimal patching but is otherwise fully usable.

Thanks to Slava Pestov for the idea!

54864f858c [Type checker] Replace a use of GenericSignatureBuilder::resolveArchetype(). 
The type checker shouldn’t know about potential archetypes. Use
GenericSignatureBuilder::resolveEquivalenceClass() and perform the lookup
into that instead.

The test case change highlights an existing problem with generic signature
minimization.
