[PATCH] Replace the bitfield of SubtargetFeatures with a BitVector

[Vladimir Sukharev]

Oops, this way it's currently impossible to refactor AArch64 backend in this manner. r207742 introduced bug - misusing these two types. 
Currently, both types are used for Mappers initialization, that's wrong.

- https://github.com/llvm-mirror/llvm/blob/master/lib/Target/AArch64/AsmParser/AArch64AsmParser.cpp#L2624
- https://github.com/llvm-mirror/llvm/blob/master/lib/Target/AArch64/InstPrinter/AArch64InstPrinter.cpp#L1279

I am working on the fix now. After it, your refactoring will be possible.
