that predated -fast-isel which attempted to speed up the dag pattern
matchers at -O0. Since fast-isel is around, this is basically
obsolete and removing it shrinks the generated dag isels.

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.

matcher is now free of implicit operands!
- Still need to clean up the code now that we don't to worry about implicit
operands, and to make it a hard error if an instruction fails to specify all
of its operands for some reason.

as a c expression that will be blatted out to the .inc

parsing C code :).

code movement, but leaves the implementation unchanged. I'll
make any changes necessary to generalize the code in a
separate patch.

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.

match orders will be a hard error, but we aren't there yet).

defining REGISTERS_ONLY before including GenAsmMatcher.inc.
This sets the stage for target-specific lexers that can
identify registers and return AsmToken::Register as
appropriate.
