cf5424b617 [GSB] Move the Recursive(Concrete|Superclass)Type bits into EquivalenceClass. 
Recursive concrete and superclass constraints are detected
per-equivalence-class; record them that way.

Use that information to drop recursive concrete and superclass
constraints from the resulting signature, which frees the canonical
generic signature builder from having to worry about such recursive
constraints. This eliminates the invalid-code crashes introduced in
the prior commit that disabled finalization for the canonical GSBs, as
well as fixing one other random crash-on-invalid.

ecdc993881 [Type checker] Tolerate invalid expressions in the error-handling checker. 
When errors occur in the processing of expressions, we can end up with
invalid ASTs where the application of an operator declared within a
type is missing its "self" argument. Tolerate such ASTs in the
error-handling checker.

ddaccf88bb [QoI] Properly diagnose closure parameter distructuring after SE-0110 
Swift 3 supported limited argument destructuring when it comes to
declaring (trailing) closures. Such behavior has been changed by
SE-0110. This patch aims to provide better error message as well
as fix-it (if structure of the expected and actual arguments matches)
to make the migration easier and disambiguate some of the common
mistakes.

2fe863266c AST: Fix crashes when name lookup finds declarations outside of a protocol or extension that's nested in another type 
When performing a name lookup from inside of a protocol
or extension, skip directly to the source file context
when we are done visiting the protocol or extension.

Otherwise, if we have invalid code where the protocol
or extension is nested inside another type, we might
find a member whose type contains generic parameters
of the outer type; these parameters will not resolve,
since we do not model protocols or extensions nested
inside generic contexts (yet?).

This supercedes an earlier workaround for a similar
issue; the new workaround fixes more crashes.

This is needed to avoid crasher regressions with an
upcoming patch.

3dbfa9789f [Associated type inference] Check solutions against full requirement signature 
When we have a potential assignment of associated types to type
witnesses during associated type inference, check that set of type
witnesses against the requirements in the requirement signature, so
that we can reject any solutions that fail some of the protocol's
requirements.

This is most of rdar://problem/31830524 --- but gets thwarted by the
inability of associated type inference to work across multiple
protocols.

aaca0badf9 Sema: Diagnose invalid references to type alias members of unbound generic types 
Consider the following setup:

struct GenericStruct<T> {
  typealias Dependent = T
  typealias Concrete = Int
}

We have no way to model 'GenericStruct.Dependent' in the AST, so the
reference would crash. Instead, produce a diagnostic suggesting to
insert generic parameters, like 'GenericStruct<Int>.Dependent'.

The reference 'GenericStruct.Concrete' is fine though, and should
not crash; add a test that it works.

Fixes <https://bugs.swift.org/browse/SR-4390>, <rdar://problem/31480755>.

9319a531f2 AST: Stricter contract for Type::subst() 
Fix an odd corner case when UseErrorTypes was off; we would
return the empty type if dependent member type substitution
failed, but otherwise return the original type if it was a
generic type parameter or an archetype.

Now, if UseErrorTypes is off, return the empty type in both
cases, even if the original type is 'primary'.

0f0a5906d7 [GSB] Put conformance requirements on the proper potential archetype. 
We were putting conformance requirements on the representative of the
equivalence class, rather than directly on the potential archetype on
which the conformance requirement was specified. This violates the
invariant used when forming protocol-requirement sources that we never
reseat a requirement onto the representative (which would
have become a problem when implementing recursive protocol
constreaints) as well as masking a GSB idempotency issue that comes
from same-type requirements where the right-hand side was not
guaranteed to refer to the archetype anchor *within* that subcomponent.

f9d6a3ce00 [swiftc (35 vs. 5512)] Add crasher in swift::TypeChecker::checkGenericParamList 
Add test case for crash triggered in `swift::TypeChecker::checkGenericParamList`.

Current number of unresolved compiler crashers: 35 (5512 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `Impl->GenericParams.empty() || ((Key.Depth == Impl->GenericParams.back()->getDepth() && Key.Index == Impl->GenericParams.back()->getIndex() + 1) || (Key.Depth > Impl->GenericParams.back()->getDepth() && Key.Index == 0))` added on 2017-02-07 by you in commit 0c76a9d8 :-)

Assertion failure in [`lib/AST/GenericSignatureBuilder.cpp (line 2127)`](4463bb8287/lib/AST/GenericSignatureBuilder.cpp (L2127)):

```
Assertion `Impl->GenericParams.empty() || ((Key.Depth == Impl->GenericParams.back()->getDepth() && Key.Index == Impl->GenericParams.back()->getIndex() + 1) || (Key.Depth > Impl->GenericParams.back()->getDepth() && Key.Index == 0))' failed.

When executing: void swift::GenericSignatureBuilder::addGenericParameter(swift::GenericTypeParamType *)
```

Assertion context:

```c++
  return ResolvedType::forPotentialArchetype(pa);
}

void GenericSignatureBuilder::addGenericParameter(GenericTypeParamDecl *GenericParam) {
  addGenericParameter(
     GenericParam->getDeclaredInterfaceType()->castTo<GenericTypeParamType>());
}

bool GenericSignatureBuilder::addGenericParameterRequirements(
                                           GenericTypeParamDecl *GenericParam) {
  GenericParamKey Key(GenericParam);

b6d7e5659d [swiftc (32 vs. 5511)] Add crasher in swift::TypeChecker::substMemberTypeWithBase 
Add test case for crash triggered in `swift::TypeChecker::substMemberTypeWithBase`.

Current number of unresolved compiler crashers: 32 (5511 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `(!Parent || Parent->is<NominalType>() || Parent->is<BoundGenericType>() || Parent->is<UnboundGenericType>()) && "parent must be a nominal type"` added on 2016-11-03 by you in commit 5780a9f52 :-)

Assertion failure in [`lib/AST/ASTContext.cpp (line 2695)`](6f8adcc56a/lib/AST/ASTContext.cpp (L2695)):

```
Assertion `(!Parent || Parent->is<NominalType>() || Parent->is<BoundGenericType>() || Parent->is<UnboundGenericType>()) && "parent must be a nominal type"' failed.

When executing: static swift::NominalType *swift::NominalType::get(swift::NominalTypeDecl *, swift::Type, const swift::ASTContext &)
```

Assertion context:

```c++
  assert((isa<ProtocolDecl>(D) || !D->getGenericParams()) &&
         "must be a non-generic type decl");
  assert((!Parent || Parent->is<NominalType>() ||
          Parent->is<BoundGenericType>() ||

297bf9a469 [swiftc (24 vs. 5511)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 24 (5511 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 1045)`](fba882ff21/lib/AST/Type.cpp (L1045)):

```
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;
  }

ecdcac5aa2 Resolve crasher 28704 (#8158) 
This crash happens because shouldAddSelfFixit (a check for the expected_self_before_reference diagnotic) performs name lookup inside the parser, which causes a search for extensions, which triggers the mangler, which can get confused if we are in an unfinished declaration (a PatternBindingInitilizer in this case).

A cleaner fix would be to move that logic inside Sema, but it would require much more refactoring that I don’t feel comfortable doing. Instead, this band-aid checks if the innermost type is inside a local context. If that’s the case, we can ignore the search for extensions.
