dccd240998 Preliminary patch to improve dwarf EH generation - Hooks to return Personality / FDE / LSDA / TType encoding depending on target / options (e.g. code model / relocation model) - MCIzation of Dwarf EH printer to use encoding information - Stub generation for ELF target (needed for indirect references) - Some other small changes here and there

d7470aa340 revert r96241. It breaks two regression tests, isn't documented, 
and the testcase needs improvement.

b5fe25544c Split SelectionDAGISel::IsLegalAndProfitableToFold to 
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.

isInteger, we now have isFloatTy and isIntegerTy.  Requested by Chris!

9436d20d76 Drop winmcasminfo and use normal AT&T COFF for all windows targets. 
Otherwise AT&T asm printer is used with non-compatible MCAsmInfo and
there is no way to override this behaviour.

6eb7ff5bbf Teach MachineFrameInfo to track maximum alignment while stack objects are being 
created. This ensures it's updated at all time. It means targets which perform
dynamic stack alignment would know whether it is required and whether frame
pointer register cannot be made available register allocation.
This is a fix for rdar://7625239. Sorry, I can't create a reasonably sized test
case.

d4fe983f23 rip out the 'heinous' x86 MCCodeEmitter implementation. 
We still have the templated X86 JIT emitter, *and* the
almost-copy in X86InstrInfo for getting instruction sizes.
