Fix crasher due to use-after-release: DeclContext now owns all ObjCMethodDecls, and shouldn't be released elsewhere.

C++ handle anonymous structs/unions in the same way. Addresses several
bugs:

  <rdar://problem/6259534>
  <rdar://problem/6481130>

The test case in PR clang/1750 now passes with -fsyntax-only, but
CodeGen for inline assembler still fails.

- Refactor a bunch of logic in the retain/release checker, making it more
  condense and easier to read.
- Add support for "Create" methods in the DiskArbitration framework

retain/release tests:
- Rename CFDate.m to retain-release.m, and move test from CFString.c to
  retain-release.m
- Add DiskArbitration framework tests cases.
- Add/refine and few more retain/release GC test cases.

There is still some work to do in Objective-C++, but this requires
that each of the Objective-C entities (interfaces, implementations,
etc.) to be introduced into the context stack with
PushDeclContext/PopDeclContext. This will be a separate fix, later.

that is neither a definition nor a forward declaration and where X has
not yet been declared as a tag, introduce a declaration
into the appropriate scope (which is likely *not* to be the current
scope). The rules for the placement of the declaration differ slightly
in C and C++, so we implement both and test the various corner
cases. This implementation isn't 100% correct due to some lingering
issues with the function prototype scope (for a function parameter
list) not being the same scope as the scope of the function
definition. Testcase is FIXME'd; this probably isn't an important issue.

Addresses <rdar://problem/6484805>.

- Refactor caching logic into a helper class PTHSpellingSearch
- Allow "random accesses" in the spelling cache, thus catching the remaining
  cases where 'getSpelling' wasn't hitting the PTH cache
  
For -Eonly, PTH, Cocoa.h:
- This reduces wall time by 3% (user time unchanged, sys time reduced)
- This reduces the amount of paged source by 1112K.
  The remaining 1112K still being paged in is from somewhere else
  (investigating).
