92ee821fe2 [swiftc (123 vs. 5249)] Add crasher in swift::GenericFunctionType::get 
Add test case for crash triggered in `swift::GenericFunctionType::get`.

Current number of unresolved compiler crashers: 123 (5249 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `!input->hasTypeVariable() && !output->hasTypeVariable()` added on 2013-10-03 by you in commit 12e228c0f :-)

Assertion failure in [`lib/AST/ASTContext.cpp (line 3026)`](https://github.com/apple/swift/blob/master/lib/AST/ASTContext.cpp#L3026):

```
Assertion `!input->hasTypeVariable() && !output->hasTypeVariable()' failed.

When executing: static swift::GenericFunctionType *swift::GenericFunctionType::get(swift::GenericSignature *, swift::Type, swift::Type, const swift::AnyFunctionType::ExtInfo &)
```

Assertion context:

```
GenericFunctionType::get(GenericSignature *sig,
                         Type input,
                         Type output,
                         const ExtInfo &info) {
  assert(sig && "no generic signature for generic function type?!");
  assert(!input->hasTypeVariable() && !output->hasTypeVariable());

  llvm::FoldingSetNodeID id;
  GenericFunctionType::Profile(id, sig, input, output, info);

  const ASTContext &ctx = input->getASTContext();
```

63178e84d2 AST: Improve robustness with invalid nesting of extensions in generic context 
Extensions cannot capture generic parameters from outer contexts.
Their generic parameter list does not point to the outer
parameter list, the signature does not contain outer parameters
and they do not appear in the extension's generic environment.

Furthermore, the depth/index of the extension's parameters may
clash with outer parameters, which would break all kinds of
invariants.

This patch changes these DeclContext methods to return false or
nullptr even if an extension is contained in a generic context:

- isGenericContext()
- getGenericParamsOfContext()
- getGenericSignatureOfContext()
- getGenericEnvironmentOfContext()

6c7277be2c [Type checker] Work around issues with badly broken generic code. 
The GenericTypeOrArchetypeResolver changes are effectively porting
some existing hacks from the now-dead
PartialGenericTypeOrArchetypeResolver, which dodges some regressions
in the compiler-crashers suite and fixes 11 new crashers. There is
undoubtedly a more principled approach to fix these problems, most of
which now step from recursively looking for a generic environment that
isn't there, but doing so requires improvements to our name lookup.

The generic environment of a GenericTypeToArchetypeResolver may be

top level.

1a991da16d AST: Assign interface types to ParamDecls 
First, ensure all ParamDecls that are synthesized from scratch are given
both a contextual type and an interface type.

For ParamDecls written in source, add a new recordParamType() method to
GenericTypeResolver. This calls setType() or setInterfaceType() as
appropriate.

Interestingly enough a handful of diagnostics in the test suite have
improved. I'm not sure why, but I'll take it.

The ParamDecl::createUnboundSelf() method is now only used in the parser,
and no longer sets the type of the self parameter to the unbound generic
type. This was wrong anyway, since the type was always being overwritten.
This allows us to remove DeclContext::getSelfTypeOfContext().

Also, ensure that FuncDecl::getBodyResultTypeLoc() always has an interface
type for synthesized declarations, eliminating a mapTypeOutOfContext()
call when computing the function interface type in configureInterfaceType().

Finally, clean up the logic for resolving the DynamicSelfType. We now
get the interface or contextual type of 'Self' via the resolver, instead
of always getting the contextual type and patching it up inside
configureInterfaceType().

c98295357c [Archetype builder] Simplify handling of typealiases in protocols. 
PotentialArchetype::getNestedType() was effectively reimplementing a
simplified form of mapTypeOutOfContext(), missing some cases in the
process. Just use mapTypeOutOfContext() and resolveArchetype(). While
here, stop re-implementing the addSameType* operations; just call them
directly. With these changes, we no longer need the "typealias in
protocol is too complex" diagnostic.

Eliminates another use of getSelfTypeInContext().

2ff9994313 Sema: Improve circularity checks 
The previous patches regressed a test where we used to diagnose
(poorly) a circular associated type, like so:

  associatedtype e: e

With the error "inheritance from non-protocol, non-class type 'e'".

This error went away, because we end up not setting the interface
type of the associated type early enough. Instead, we return an
ErrorType from resolveTypeInContext() and diagnose nothing.

With this patch, emit a diagnostic at the point where the ErrorType
first appears.

Also, remove the isRecursive() bit from AssociatedTypeDecl, and
remove isBeingTypeChecked() which duplicates a bit with the same
name in Decl.

589b469484 [AST] Extend a hack to work around broken circular inheritance checking. 
Extending this hack recovers a regression in a previously-fixed
compiler crasher (#26725), and fixes two more compiler crashers. So,
despite it's utter lack of principle, it's progress.

6cbb494ad2 AST: Give all ValueDecls an interface type 
Previously, getInterfaceType() would return getType() if no
interface type was set. Instead, always set an interface type
explicitly.

Eventually we want to remove getType() altogether, and this
brings us one step closer to this goal.

Note that ParamDecls are excempt from this treatment, because
they don't have a proper interface type yet. Cleaning this up
requires more effort.

d111e9b4be [Diagnostics] When building a subscript don't assume that overload is always present 
This handles situation when overload for the subscript hasn't been resolved
by constraint solver, such might happen, for example, if solver was allowed to
produce solutions with free or unresolved type variables (e.g. when running diagnostics).

37d38abeb1 AST: Fix crashes when ordering potential archetypes arising from typealias declarations in protocols 
This fixes the oldest compiler crasher, number 46. All remaining unfixed
crashers are numbered 28155 and above.
