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.

Fixes <https://bugs.swift.org/browse/SR-2616> and
<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.

05411fc8c1 [swiftc (34 vs. 5527)] Add crasher in swift::ProtocolDecl::findProtocolSelfReferences 
Add test case for crash triggered in `swift::ProtocolDecl::findProtocolSelfReferences`.

Current number of unresolved compiler crashers: 34 (5527 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 1787)`](69d69c723b/lib/AST/Decl.cpp (L1787)):

```

When executing: swift::Type swift::ValueDecl::getInterfaceType() const
```

Assertion context:

```c++

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

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

void ValueDecl::setInterfaceType(Type type) {

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.

bc7dff5c9f Revert "Re-instate "Improve disjunction selection"" 
This reverts commit
ecfa406fc5, which was reinstating
3c5b393e0c.

It does not revert one test change from that commit, because
inexplicably one of the tests is still failing, probably due to some
other changes that have happened since. I'm leaving a ticket open to
investigate.

I've added one of the new cases that is failing as a result of this
change.

This is being reverted not because of bugs in this particular commit,
but because it seems to be exposing other bugs in the type checker that
are resulting in source compatibility problems. We need to shake these
other bugs out of the type checker before bringing this change back.

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `false && "Should have found context by now"` added on 2016-12-06 by you in commit fdaa88606 :-)

This doesn't give particularly useful information yet (i.e. Self isn't
listed, see rdar://problem/31981641 ), but it does stop the completion
code from just directly crashing.

Fixes rdar://problem/31981486.
