x86emul: deliver correct math exceptions

#MF only applies to x87 instructions. SSE and AVX ones need #XM to be
raised instead, unless CR4.OSXMMEXCPT is clear, in which case #UD needs
to result. (But note that this is only a latent issue - we don't
emulate any instructions so far which could result in #XM.)
