of a mneumonic, report operand errors with better location
info. For example, we now report:

cwtl $1
^
but we fail for common cases like:
t.s:11:4: error: invalid operand for instruction
addl $1, $1
^
because we don't know if this is supposed to be the reg/imm or imm/reg
form.

have tblgen detect when an instruction would have matched, but

failed because a subtarget feature was not enabled. Use this to
remove a bunch of hacks from the X86AsmParser for rejecting things

when used in the wrong mode.
This also fixes bugs where pushal would not be rejected correctly in
32-bit mode (just pusha).
