[PATCH 0/6] x86: AVX512* / EVEX decoding adjustments

[Jan Beulich]

This carries out a few things which were mentioned previously, plus
a few more adjustments noticed as desirable along the way.

1: reduce AVX512-FP16 set of insns decoded through vex_w_table[]
2: reduce AVX512 FP set of insns decoded through vex_w_table[]
3: record further wrong uses of EVEX.b
4: consistently use scalar_mode for AVX512-FP16 scalar insns
5: share yet more VEX table entries with EVEX decoding
6: drop ymmxmm_mode
