a3c2f8be5b [swiftc (71 vs. 5114)] Add crasher in swift::TypeChecker::lookupMemberType(...) 
Add test case for crash triggered in `swift::TypeChecker::lookupMemberType(...)`.

Current number of unresolved compiler crashers: 71 (5114 resolved)

Assertion failure in [`lib/Sema/TypeCheckNameLookup.cpp (line 328)`](https://github.com/apple/swift/blob/master/lib/Sema/TypeCheckNameLookup.cpp#L328):

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

When executing: swift::LookupTypeResult swift::TypeChecker::lookupMemberType(swift::DeclContext *, swift::Type, swift::Identifier, NameLookupOptions)

Assertion context:

```
  // Look through the metatype.

758cf64283 Rework access checking in terms of "access scopes". 
(in preparation for the private/fileprivate split)

An "access scope" is the outermost DeclContext where a particular
declaration may be referenced: for a 'fileprivate' declaration it's
the enclosing file, and for an 'internal' declaration it's the module.
'public' corresponds to a scope of "everything", represented by a null
DeclContext.

This model extends naturally to the (not-yet-implemented) SE-0025
notion of 'private', where the access scope is a declaration's
immediately enclosing DeclContext.

Complicating this model is the revised rules that allow, e.g., a public
declaration to be declared within an internal type. The access scope
for this declaration is still just the module, not "everything".

This commit reworks formal access control checking in terms of this
model, including tightening up some of the handling for '@testable'.
This implements the rule that you must be able to access a declaration's
type everywhere you can reference the declaration.

This was not intended to change compiler behavior, but in practice it
has made cross-file dependency tracking a bit more conservative
(unnecessarily), caught a mistake in diagnosing access violations,
and fixed a fuzzer-based crasher (see test changes).

Progress on SE-0025 ('private' and 'fileprivate')

c56f96d237 [Type checker] Synthesize member operator '==' for Equatable enums. 
Rather than synthesizing a global operator '==' for Equatable enums,
synthesize a member operator, which is more idiomatic and much
cleaner.

To make sure that these synthesized operators can actually be found,
start considering operator requirements in protocols
more generally in the type checker, so that, e.g., "myEnum == myEnum"
will type-check against Equatable.== and, on successful type-check,
will call the (newly-synthesized) witness for '=='. This both makes it
easier to make sure we find the operators in, e.g., complex multi-file
and lazy-type checking scenarios, and is a step toward the
type-checking improvements described in SE-0091.

80f0852504 [SE-0091] Allow 'static' operators to be declared within types and extensions thereof. 
Allow 'static' (or, in classes, final 'class') operators to be
declared within types and extensions thereof. Within protocols,
require operators to be marked 'static'. Use a warning with a Fix-It
to stage this in, so we don't break the world's code.

Protocol conformance checking already seems to work, so add some tests
for that. Update a pile of tests and the standard library to include
the required 'static' keywords.

There is an amusing name-mangling change here. Global operators were
getting marked as 'static' (for silly reasons), so their mangled names
had the 'Z' modifier for static methods, even though this doesn't make
sense. Now, operators within types and extensions need to be 'static'
as written.

5bb61795b6 Mark decls that are illegal due to generic inside non-generic decl or non-generic inside generic decl with setInvalid(), and avoid assertions 
trying to set the superclass on classes in such situations by setting the superclass of an invalid decl to the error type.

This fixes a bunch of compiler crashes, and also changes some errors in other tests where the main error is the invalid declaration and now the
downstream errors can be a bit different because the decl has been invalidated.

5a902935e8 Sema: Explicitly set interface type on all AbstractFunctionDecls 
Previously getInterfaceType() would punt to getType() if no
interface type was set. This patch changes getInterfaceType()
to assert if no interface type is set, and updates various
places to set the interface type explicitly.

This brings us a step closer to removing PolymorphicFunctionType.
