whose opcodes extend into the ModR/M field using the
Form field of the instruction rather than by special
casing each instruction.  Commented out the special
casing of VMCALL, which is the first instruction to use
this special form.  While I was in the neighborhood,
added a few comments for people modifying the Intel
disassembler.

This will work better for the disassembler for modeling things
like lfence/monitor/vmcall etc.

   of its operands for some reason.

This time it's for real! I am going to hook this up in the frontends as well.

The inliner has some experimental heuristics for dealing with the inline hint.
When given a -respect-inlinehint option, functions marked with the inline
keyword are given a threshold just above the default for -O3.

We need some experiments to determine if that is the right thing to do.

This sets the stage for target-specific lexers that can
identify registers and return AsmToken::Register as
appropriate.
