- 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.

- 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).

of ScopedDecls (using the new ScopedDecl::NextDeclInScope
pointer). Performance-wise:

  - It's a net win in memory utilization, since DeclContext is now one
    pointer smaller than it used to be (std::vectors are typically 3
    pointers; we now use 2 pointers) and 
  - Parsing Cocoa.h with -fsyntax-only (with a Release-Asserts Clang)
    is about 1.9% faster than before, most likely because we no longer
    have the memory allocations and copying associated with the
    std::vector.

I'll re-enable serialization of DeclContexts once I've sorted out the
NextDeclarator/NextDeclInScope question.

type of the declaration and a run-time predicate described by a member
function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl
considerably. It has no measurable performance impact.
