55ffbe8cce AST: Fix Type::transform() for protocol compositions 
There was undefined behavior here; we were calling
members.append(members.begin(), members.begin() + index),
which is invalid because 'members' is the new array of
members being built, which is empty at this point!

6a3d57378b [swiftc (37 vs. 5544)] Add crasher in swift::TypeChecker::checkDeclAttributesEarly(...) 
Add test case for crash triggered in `swift::TypeChecker::checkDeclAttributesEarly(...)`.

Current number of unresolved compiler crashers: 37 (5544 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `loc.isValid() && "Diagnosing attribute with invalid location"` added on 2017-04-22 by you in commit 25ce6fa2 :-)

Assertion failure in [`lib/Sema/TypeCheckAttr.cpp (line 39)`](df10b0fe02/lib/Sema/TypeCheckAttr.cpp (L39)):

```
Assertion `loc.isValid() && "Diagnosing attribute with invalid location"' failed.

When executing: void (anonymous namespace)::diagnoseAndRemoveAttr(swift::TypeChecker &, swift::Decl *, swift::DeclAttribute *, ArgTypes &&...) [ArgTypes = <swift::Diag<> &>]
```

Assertion context:

```c++
  void diagnoseAndRemoveAttr(TypeChecker &TC, Decl *D, DeclAttribute *attr,
                             ArgTypes &&...Args) {
    assert(!D->hasClangNode() && "Clang imported propagated a bogus attribute");
    if (!D->hasClangNode()) {
      SourceLoc loc = attr->getLocation();
      assert(loc.isValid() && "Diagnosing attribute with invalid location");
      if (loc.isInvalid()) {
        loc = D->getLoc();
      }
      if (loc.isValid()) {
        TC.diagnose(loc, std::forward<ArgTypes>(Args)...)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `ty->getNominalOrBoundGenericNominal() || ty->is<DynamicSelfType>() || ty->isExistentialType() || ty->is<ArchetypeType>()` added on 2014-02-25 by you in commit 6a532e05c :-)

7ef9041111 [swiftc (30 vs. 5544)] Add crasher in swift::GenericSignature::getConformanceAccessPath 
Add test case for crash triggered in `swift::GenericSignature::getConformanceAccessPath`.

Current number of unresolved compiler crashers: 30 (5544 resolved)

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

Assertion failure in [`lib/AST/GenericSignature.cpp (line 857)`](aae1b681e7/lib/AST/GenericSignature.cpp (L857)):

```
Assertion `inProtocol->isRequirementSignatureComputed() && "missing signature"' failed.

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

Assertion context:

```c++

      // Canonicalize this step with respect to the requirement signature.
      if (!inProtocol->isRequirementSignatureComputed()) {
        inProtocol->computeRequirementSignature();
        assert(inProtocol->isRequirementSignatureComputed() &&
               "missing signature");
      }

      // Get a generic signature builder for the requirement signature. This has
      // the requirement we need.
      auto reqSig = inProtocol->getRequirementSignature();
```

63bc717963 Error when one associated type is constrained to another. (#10053) 
(...is constrained to be a subtype of another)

Previously the compiler would just mark the entry in the inheritance
clause invalid and move on without emitting any errors; in certain
circumstances in no-asserts builds this could actually lead to
everything working "correctly" if all conforming types happened to
pick the same concrete type for both associated types. In Swift 4 this
can actually be enforced with a same-type requirement, which will
guarantee that the two associated types are the same even in generic
contexts.

This fix avoids assertions and crashes, but the diagnostic is still
incorrect, and in the simple case of the inheritance clause it's
redundant. Doing something better and possibly even downgrading it to
a warning in Swift 3 mode is tracked by rdar://problem/32409449.

Initial patch by Slava, fixed up by me.

a9733cb8db [GSB] Resolve dependent member types in same-type and superclass constraints. 
Once we're finalizing same-type-to-concrete and superclass
constraints, replace any unresolved DependentMemberTypes with their
resolved counterpairs. This allows us to simplify
DependentGenericTypeResolver, which only builds unresolved
DependentMemberTypes now, and eliminates the penultimate use of
ArchetypeResolutionKind::AlwaysPartial.

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!valueType->hasUnboundGenericType() && !valueType->hasTypeParameter()` added on 2017-05-22 by you in commit b112e95a :-)

Assertion failure in [`lib/Sema/ConstraintSystem.cpp (line 841)`](a290776ff0/lib/Sema/ConstraintSystem.cpp (L841)):

```

fc21ecce68 AST: Don't return hasTypeParameter() for DependentMemberTypes with an ErrorType base 
Instead, introduce a new hasDependentMember() recursive property.

The only place that cares about this is associated type inference,
where I changed all existing hasTypeParameter() checks to instead
check (hasTypeParameter() || hasDependentMember()). We could
probably refine this over time and remove some of the
hasTypeParameter() checks, but I'm being conservative for now.

d8234bace6 Sema: Fix double type checking of lazy initializer expressions 
If a lazy var has no declared type, we have to type check the
initializer to get a type before we can build the getter.

Then, the initializer is type checked as part of the getter
again.

Use the new SkipApplyingSolution flag when type checking for
the first time. We still end up doing redundant work, but by
not applying the solution we avoid feeding invalid AST nodes
back into the constraint solver.

This fixes some bad diagnostics and crashes.

<rdar://problem/28313602>.

fa155bf1d1 Sema: Rework typeCheckBinding() to use the new foundSolution() callback 
Record the initializer type as soon as we have a solution, before
it is applied, and get the type from the constriant system instead
of from the final type checked expression.

Note that the coerceToMaterializable() was unnecessary, since we
always coerce the value to an rvalue type with coerceToType().

Eventually coerceToMaterializable() should go away.

This is mostly NFC, except using the result of simplifyType() rather
than the type of the final expression changes some diagnostics where it
appears we were previously losing sugar.

Also this accidentally fixes a crasher. Unfortunately the underlying
issue is still there (applying a solution has bugs with opened
existentials "leaking" out) -- this merely masks the problem by
getting the initializer type directly from the constriant system.

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.
