Rewriting of @synchronized. This has one FIXME in it. But this should allow @sychronized to be rewritten.

- Some minor optimizations of the encoding format for ObjCAtSynchronizedStmt.
- Reordered methods so that the deserialization methods for 
  ObjCAtSynchronizedStmt appear in alphabetical order with the corresponding
  methods of the other AST nodes.

Made some internal API cleanups with creating ConcreteInt values, which lead to
some code reduction in implementing "++", "--".

Work in progress. This patch *fixes* x86-64 calls which are modelled as StructRet but really should be return in registers, e.g. _Complex long double, some 128-bit aggregates. This is a short term solution that is necessary only because llvm, for now, cannot model i128 nor call's with multiple results.
Status: This only works for direct calls, and only the caller side is done. Disabled for now.

type that matters but the operand type.  This fixes
2008-01-08-IllegalCMP.ll which crashed with the new
legalize infrastructure because SETCC with result
type i8 and operand type i64 was being custom expanded
by the X86 backend.  With this fix, the gcc build gets
as far as the first libcall.

Tighten up ASTContext::typesAreCompatible()...it needs to make sure the qualifiers match. The comment and C99 citation for this routine were correct...the code needed to conform to the comment/spec. This fixes the test added below.

Tightening up this routine forced tweaks to Sema::CheckSubtractionOperands() and Sema::CheckCompareOperands(). For example, they both need to operate on the unqualified pointee...
