Implement "optimization" for lambda-to-block conversion which inlines the generated block literal for lambdas which are immediately converted to block pointer type.  This simplifies the AST, avoids an unnecessary copy of the lambda and makes it much easier to avoid copying the result onto the heap.

Note that this transformation has a substantial semantic effect outside of ARC: it gives the converted lambda lifetime semantics similar to a block literal.  With ARC, the effect is much less obvious because the lifetime of blocks is already managed.

Fix regression from llvm-gcc where we should NOT emit a warning about __attribute__((NSObject)) on a property declaration.  This is needed to have retain properties for non-object pointers.  Fixes <rdar://problem/10930507>.

I'm not sure if this is the best way to go about it, but
I locally enabled this code path without the msext conditional,
and all tests pass, except for test/Preprocessor/cxx_oper_keyword.cpp
which explicitly checks that operator keywords can't be redefined.

I also parsed chromium/win with a clang with and without this patch.
It introduced no new errors, but removes 43 existing errors.

Unfortunately, the default TargetLibraryInfo constructor assumes all library

Teach the checker and the engine about these APIs to resolve malloc
false positives. As I am adding more of these APIs, it is clear that all
this should be factored out into a separate callback (for example,
region escapes). Malloc, KeyChainAPI and RetainRelease checkers could
all use it.

Tentatively fix PR12117. The test case from the bug now passes, and all existing tests still pass, but there may still be corner cases.

The bug that was caught by Apple's internal buildbots was valid and also showed another bug in my implementation.

These are now fixed, with regression tests added to catch them both (not Darwin-specific).

Original log:
====================

Revert r151638 because it causes assertion hit on PCH creation for Cocoa.h

Original log:
---------------------
Correctly track tags and enum members defined in the prototype of a function, and ensure they are properly scoped.

This fixes code such as:

enum e {x, y};
int f(enum {y, x} n) {
 return 0;
}

This finally fixes PR5464 and PR5477.
---------------------

I also reverted r151641 which was enhancement on top of r151638.

of the SmallPtrSet way up to avoid commonly reallocating the buffer size.
 - I didn't see a good argument against it, so I bumped the limit to cover the
   max size we see during parsing Cocoa.h.

llvm-svn: 151698

 - This reduces our total # of allocations building a PCH for Cocoa.h by almost
   a whopping 50%.
 - A SmallPtrMap would be cleaner, but since we don't have one yet...
