Changes since v1:
* No attempt to pack pos+len into one operand. Updated backends
to match this change.
* Example in the README is a bit more complex.
* Define an official tcg_scratch_alloc routine, used by the i386
target for the case in which we need a scratch register. I had
said that triggering this wasn't possible with mainline, but I
was wrong. The rlwimi example I posted in the other thread hits
this case.
Aurelien suggested using a shorter name like "dep", but I think that
would be more confusing than not. This opcode is not really used
enough to warrent cropping 4 characters, in my opinion.
