[BOLT] Introduce MCPlus layer
Summary:
Refactor architecture-specific code out of llvm into llvm-bolt.
Introduce MCPlusBuilder, a class that is taking over MCInstrAnalysis
responsibilities, i.e. creating, analyzing, and modifying instructions.
To access the builder use BC->MIB, i.e. substitute MIA with MIB.
MIB is an acronym for MCInstBuilder, that's what MCPlusBuilder used
to be. The name stuck, and I find it better than MPB.
Instructions are still MCInst, and a bunch of BOLT-specific code still
lives in LLVM, but the staff under Target/* is significantly reduced.
