Hopefully pine doesn't corrupt this patch, I've had problems recently.
For an alpha "ret" instruction, of the type
ret $26
The return was being ignored. This is because in translate.c
register $26 (the return address) was being over-written with the current
PC before it could be jumped to. Thus the ret was ignored.
This patch just re-orders things so the return address is processed before
it is over-written with the current PC.
