r600g/sb: use MULADD workaround on R7xx for MULADD_IEEE
Looks like the same issue that was seen with MULADD in trans slot on
R7xx also affects MULADD_IEEE (maybe all OP3 instructions and MULADD is
just a most frequently used?). So the workaround is to not allow affected
instructions to be placed into the trans slot.
