kreg (mask) register file shared with MMX/x87

I find that the PRF for AVX-512 mask registers (k0-k7) is apparently shared with that for x87/MMX registers.

I ran across this trying to identify all the register files from the SKX die shots, and I couldn't find a place for both the mask registers and and the x87/MMX regs. It occurred to me they could be shared...

Here's the longer version.

Discussion welcome, and let me know if you spot any typos.
