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...
