This patch fixes an obvious problem: the fma4_fmsubadd/fma4_fmaddsub
instruction templates don't generate vfmsubaddpd/vfmaddsubpd because
they don't use <ssemodesuffix>
This passes bootstrap on x86_64 on trunk. Okay to commit?
BTW, I'm testing on gcc-4_6-branch. Should I post a different patch
thread, or just use this one?
