Subject: - 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.
