Hi!
While working on the OpenMP isa patch, I've noticed most of the x86 ISA
options imply in the help text that it enables MMX, when they do not.
We now have the mmx in sse2, so to some extent most of the built-in functions
are enabled with sse2 on 64-bit targets, but we do not enable MMX code
generation and I think listing MMX in there does more harm than good,
it is something that should better be explained in the documentation.
Ok for trunk?
