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.

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.

This currently doesn't handle capturing the 'this' pointer for any
enclosing class.

Steal the lambda-expressions.cpp testcase and debugify it and try
to use more variables to proof it against random changes.

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...

[analyzer diagnostics] Refactor filtration for PathDiagnosticConsumers that don't support cross-file diagnostics
into a common place.  Currently enable this filtration for Plist diagnostics as well.

llvm-svn: 151664

[analyzer diagnostics] start prototyping stripping PathDiagnostics of unnecessary cruft caused by path inlining.

This introduces a concept of a "prunable" PathDiagnosticEvent.  Currently this is a flag, but
we may evolve the concept to make this more dynamically inferred.
