5cce5c4d1d [Parser] Refactor parsing of calls and call-like expressions. 
Rather than parsing the call arguments (or similar, e.g., subscript)
as a parenthesized expression or tuple, then later reworking that
ParenExpr/TupleExpr if a trailing closure comes along, then digging
through that ParenExpr/TupleExpr to pull out the arguments and
trailing closure... just parse the expression list and trailing
closure together, then directly form the appropriate AST node with
arguments/labels/label locations/trailing closure.

Fixes rdar://problem/19804707, which is an issue where trailing
closures weren't working with unresolved member expressions (e.g.,
".foo {... }"), and is a stepping-stone to SE-0111.

7bfaeb57f1 [SE-0081] Warn on deprecated where clause inside angle brackets 
and provide a fix-it to move it to the new location as referenced
in SE-0081.

Fix up a few stray places in the standard library that is still using
the old syntax.

Update any ./test files that aren't expecting the new warning/fix-it
in -verify mode.

While investigating what I thought was a new crash due to this new
diagnostic, I discovered two sources of quite a few compiler crashers
related to unterminated generic parameter lists, where the right
angle bracket source location was getting unconditionally set to
the current token, even though it wasn't actually a '>'.

1ae8e37058 Remove -enable-protocol-typealiases staging flag 
It looks like migration fixits are done, and this doesn't
expose any new bugs that were not possible before, because
you could already define typealiases inside protocol
extensions.

To prevent some compiler_crasher regressions, add a simple
circularity-breaking hack. I'll need to do a sweep to clean
these up some day soon.

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.
