Bill Nell 46866f5fa0 [BOLT] Refactor branch analysis code. ...

Summary:
Move the indirect branch analysis code from BinaryFunction to MCInstrAnalysis/X86MCTargetDesc.cpp.

In the process of doing this, I've added an MCRegInfo to MCInstrAnalysis which allowed me to remove a bunch of extra method parameters.  I've also had to refactor how BinaryFunction held on to instructions/offsets so that it would be easy to pass a sequence of instructions to the analysis code (rather than a map keyed by offset).

Note: I think there are a bunch of MCInstrAnalysis methods that have a BitVector output parameter that could be changed to a return value since the size of the vector is based on the number of registers, i.e. from MCRegisterInfo.  I haven't done this in order to keep the diff a more manageable size.
