Enhance the InstrStage object to enable the specification of an Itinerary with overlapping stages. The default is to maintain the current behavior that the "next" stage immediately follows the previous one.

leaving the mayLoad and mayStore settings around only the load/store
instructions where those can't be inferred from the patterns.

ties of TargetAsmInfo to TargetMachine, meaning that MC can now use 
TargetAsmInfo.

Add contexts to some of the MVT APIs.  No functionality change yet, just the infrastructure work needed to get the contexts to where they need to be first.

"inlineasmstart/end" strings so that the contents of the directive
are separate from the comment character.  This lets elf targets
get #APP/#NOAPP for free even if they don't use "#" as the comment
character.  This also allows hoisting the darwin stuff up to the
shared TAI class.

 - Used to mark fake instructions which don't correspond to an actual machine
   instruction (or are duplicates of a real instruction). This is to be used for
   "special cases" in the .td files, which should be ignored by things like the
   assembler and disassembler. We still need a good solution to handle pervasive
   duplication, like with the Int_ instructions.

 - Set the bit on fake "mov 0" style instructions, which allows turning an
   assembler matcher warning into a hard error.

 - -2 FIXMEs.
