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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134884 91177308-0d34-0410-b5e6-96231b3b80d8
