Make StmtDumper::VisitCXXFunctionalCastExpr dump the attached cast kind.  Fix the cast kind for a cast from floating-point to enum type.  (The difference isn't actually visible, but that's just because IRGen is overly forgiving.)  Per report by Enea Zaffanella on cfe-dev.

This changes loop unrolling to use the same mechanism for trip count
computation as indvars. This is a stronger check that tends to unroll
more loops. A very common side-effect is that many single iteration
loops will be removed sooner. The real goal was simply to remove
dependence on canonical IVs.

x86 is break even.
ARM performance changes to expect (+ is good):
External/SPEC/CFP2000/183.equake/183.equake +13%
SingleSource/Benchmarks/Dhrystone/fldry     +21%
MultiSource/Applications/spiff/spiff         +3%
SingleSource/Benchmarks/Stanford/Puzzle     -14%

The Puzzle regression is actually an improvement in loop optimization
that defeats GVN: rdar://problem/10065079.

[analyzer] Move the knowledge of whether or not GC is enabled for the current analysis from CFRefCount to ExprEngine.

Remove TransferFuncs from ExprEngine and AnalysisConsumer.

Demote RetainReleaseChecker to a regular checker, and give it the name osx.cocoa.RetainCount (class name change coming shortly). Update tests accordingly.

Make IC_VEX* not inherit from IC_*. Prevents instructions with no VEX form from disassembling to their non-VEX form. Also prevents weak filter collisons that were keeping valid VEX instructions from decoding properly. Make VEX_L* not inherit from VEX_* because the VEX.L bit always important. This stops packed int VEX encodings from being disassembled when specified with VEX.L=1. Fixes PR10831 and PR10806.

Perform the upgrading in steps.

* First, create a map of the invokes to the EH intrinsics.

* Next, take that mapping and determine if the invoke's unwind destination has a
  single predecessor. If not, then create a new empty block to hold the new
  landingpad instruction.

* Create a landingpad instruction into the uwnind destination. Fill it with the
  values from the old selector. Map the old intrinsic calls to the new
  landingpad values (there may be multiple landingpad instructions per instrinic
  call pairs).

* Go through the old intrinsic calls, create a PHI node when necessary, and then
  replace their values with the new values from the landingpad instructions.

* Delete all dead instructions.

* ???

* Profit!

Preprocessor, eliminating the constructor that was used by ASTUnit

both objects are non-NULL will simplify module loading (but none of
that is done yet).

DWARF accelerator table sections to the DWARF parser. These sections are similar
to the .debug_pubnames and .debug_pubtypes, but they are designed to be hash tables
that are saved to disc in a way that the sections can just be loaded into memory
and used without any work on the debugger side. The .debug_pubnames and .debug_pubtypes
sections are not ordered, contain a copy of the name in the section itself which
makes these sections quite large, they only include publicly exported names (so no
static functions, no types defined inside functions), many compilers put different
information in them making them very unreliable so most debugger ignore these sections
and parse the DWARF on their own. The tables must also be parsed and sorted in order 
to be used effectively. The new sections can be quickly loaded and very efficiently be used 
to do name to DIE lookups with very little up front work. The format of these new
sections will be changing while we work out the bugs, but we hope to have really 
fast name to DIE lookups soon.

will make memcpy byval easier to implement in the future.
