Handle add, adc, etc., mfence, div, idiv, mul in the assembler.

Add a test to check that the encodings are efficient for immediates
(chooses the i8, and eax encodings when appropriate).

The .byte syntax breaks NaCl bundle straddle checking in llvm-mc,
so I had to change one of the tests which noted that a nop appeared
(no longer does).

This also assumes that _add(), etc. are usually done with _add(T, ...) and
then _mov(dst, T) so that the dest is always register.
