it passed all tests in the openpower-isa repo on my computer, so I assumed that
means I didn't break anything.

i'll work on moving all those sv.* special cases to CUSTOM_INSNS and add the
apprpriate sv.*. mnemonics tomorrow, that should be a good cleanup.

since fmadds. specifically is a v3.0b op, sending it straight to gas should
work fine, no special case should be needed.
