The attached patch should implement most of the missing opcodes. About
the only ones it doesn't do are the MASKMOVxxx ones as they are quite
horrible and involved an implicit reference to EDI so I need to think
about them a bit more.

The patch also includes a set of tests for the MMX/SSE/SSE2 opcodes to
validate that they have the same effect under valgrind as they do when
run normally. In one or two cases this wasn't actually the case even
for some of the implemented opcodes, so I fixed those as well ;-)
