Just got some initial results. I have not yet built it into the full gemm,
but the kernel timing looks very good:
dmm : 995
zmm : 915
smm : 1039
cmm : 1025
So it looks like zmm has taken the biggest hit, which doesn't make a lot of
sense to me. Julian's nasm kernel is getting 960 for dmm, so I'm thinking I
must have an old .o or something . . .
Anyway, if these numbers hold up for full gemm, this looks plenty good for the
stable to me . . .
