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.

Allow operator keywords to be #defined in ms-ext mode.
...
Fixes PR10606.
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.

Allocate TargetLibraryInfo for the CodeGen passes. Otherwise, it's instantiated

Unfortunately, the default TargetLibraryInfo constructor assumes all library

[analyzer] Malloc: A pointer might escape through CFContainers APIs,
...
funopen, setvbuf.
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.

Reapply r151638 and r151641.

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.
