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

- 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.

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.

Revert earlier unnecessary hack. Make sure we correctly force on 64bit and cmov for 64-bit targets.

Default 64-bit target features and SSE2 on when a triple specifies x86-64. Clean up all the other hacks which are now unnecessary.

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".
