As with the other patches, these need to follow the naming convention:

POOL32F_<misc>_FM
lib/Target/Mips/MicroMips32r6InstrInfo.td
71–89

The double precision instructions should have a '_D' in the same way as the single precision ones have '_S'

Also, there's some inconsistency in where the '_S' appears in these. Most have it before the 'MMR6' but a couple have it after.
