- Fix regression reported in <rdar://problem/6452745>.  After a null check, null references to resources should not have a retain count.  This regression was caused by removing the call to "GRTransferFuncs::EvalAssume" in BasicConstraintManager.
- Added a test case to test this behavior.

Note that one test duplicate-ivar-check.m will fail because I 
need to re-implement duplicate ivar checking.

- ability to insert previously created instructions using a builder
- creation of aliases
- creation of inline asm constants

- Because of the introduction of AnonTypedRegions when reasoning about casts, we
  had a regression in the "symbolication" of variable values passed-by-reference
  to a function. This is now fixed in CFRefCount.cpp (-checker-cfref) by
  blasting through the layer of AnonTypedRegions when symbolicating the value of
  the variable. This logic may get moved elsewhere. Note that this change
  affects only -checker-cfref and not -checker-simple; eventually this logic
  should get pulled out of CFRefCount.cpp into a more common place. All users
  use -checker-cfref by default, and -checker-simple should probably just be
  removed.  
- Updated test 'Analysis/uninit-vals-ps.c' to only use -checker-cfref and added
  a test case for this regression.

Improved on property diagnostics.
Added a FIXME per Steve's comments.

llvm-svn: 61141

Make the injected-class-name of a C++ class a separate RecordDecl from the class itself, with a different scope. This eliminates some ownership issues, so that the RecordDecl only lives in a single context

  warning: statement was disambiguated as declaration

because it is currently firing in cases where the declaration would
not actually parse as a statement. We'd love to bring this warning
back if we can make it more accurate.

Fix <rdar://problem/6450964> clang on xcode: Assertion failed: (RecordForDecl && "lookupFieldDeclForIvar no storage for class").

This was a recent regression caused by r61043 (related to code gen. for ivar references).

Fariborz, please review. I have some other concerns related to code generation for ivars that we can discuss later.

load from a pointer global wants to be SRAd but the load is used
by (recursive) phi nodes.  This fixes a pessimization on ppc
introduced by Load PRE.

temporary workaround for an obscure bug. When node cloning is
used, it is possible that more SUnits will be created, and
if the SUnits std::vector has to reallocate, it will
invalidate all the graph edges.
