439661395f Introduce MCCodeGenInfo, which keeps information that can affect codegen
(including compilation, assembly). Move relocation model Reloc::Model from
TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

0e6a052331 Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo down
to MCRegisterInfo. Also initialize the mapping at construction time.

This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step
towards fixing the layering violation.

1be0e271a0 Move some parts of TargetAsmInfo down to MCAsmInfo. This is not the greatest
solution but it is a small step towards removing the horror that is
TargetAsmInfo.

4afa2b842b Major update to CMake build to reflect changes in r135219 in the
backend. Moved some MCAsmInfo files down into the MCTargetDesc
sublibraries, removed some (i suspect long) dead files from other parts
of the CMake build, etc. Also copied the include directory hack from the
Makefile.

Finally, updated the lib deps. I spot checked this, and think its
correct, but review appreciated there.

1abf2cb59b Rename createAsmInfo to createMCAsmInfo and move registration code to MCTargetDesc to prepare for next round of changes.

c60f9b7523 Next round of MC refactoring. This patch factor MC table instantiations, MC
registeration and creation code into XXXMCDesc libraries.

59ee62d241 - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfo
and MCSubtargetInfo.
- Added methods to update subtarget features (used when targets automatically
  detect subtarget features or switch modes).
- Teach X86Subtarget to update MCSubtargetInfo features bits since the
  MCSubtargetInfo layer can be shared with other modules.
- These fixes .code 16 / .code 32 support since mode switch is updated in
  MCSubtargetInfo so MC code emitter can do the right thing.

ffc0e73046 Change createAsmParser to take a MCSubtargetInfo instead of triple,
CPU, and feature string. Parsing some asm directives can change
subtarget state (e.g. .code 16) and it must be reflected in other
modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance
must be shared.

ebdeeab812 Eliminate asm parser's dependency on TargetMachine:
- Each target asm parser now creates its own MCSubtatgetInfo (if needed).
- Changed AssemblerPredicate to take subtarget features which tablegen uses
  to generate asm matcher subtarget feature queries. e.g.
  "ModeThumb,FeatureThumb2" is translated to
  "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0".
