--- Comment #3 from Jacob Lifshay <programmerjake at gmail.com> ---
I allocated draft opcode encodings for fmvfg[s]/fmvtg[s]/fcvtfg[s]/fcvttg[o][s]
I verified fcvttg[s] don't collide with anything in v3.1B since they're not on
the fptrans tables.

    allocate fmv/fcvt draft opcodes

I made space by commenting out all the fmin/fmax ops since they're being
replaced, ghostmansd can finish that off later. Also some misc cleanup/fixes:

    remove testing with INSNDB=true since that now does nothing different

    comment fmin*/fmax* since they're being replaced with fminmax and to make
space for fmv/fcvt
