MC/X86: Chris pointed that 'as' isn't consistent in accepting the long form of
...
instructions which have no direct register usage.
Darwin 'as' accepts:
add $0, (%rax)
but rejects
mov $0, (%rax)
for example.
Given that, only accept suffix matches which match exactly one form. We still
need to emit nice diagnostics for failures...

MC/X86: Add "support" for matching ATT style mnemonic prefixes.
...
- The idea is that when a match fails, we just try to match each of +'b', +'w',
+'l'. If exactly one matches, we assume this is a mnemonic prefix and accept
it. If all match, we assume it is width generic, and take the 'l' form.
- This would be a horrible hack, if it weren't so simple. Therefore it is an
elegant solution! Chris gets the credit for this particular elegant
solution. :)
- Next step to making this more robust is to have the X86 matcher generate the
mnemonic prefix information. Ideally we would also compute up-front exactly
which mnemonic to attempt to match, but this may require more custom code in
the matcher than is really worth it.

include the 32 of PUSH32 since they actually push the size of the stack pointer.
