in the case where an instruction only has one implementation
of a mneumonic, report operand errors with better location
info. For example, we now report:
t.s:6:14: error: invalid operand for instruction
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.
