[PATCH v2 0/4] x86/APX: respect -msse2avx

[Jan Beulich]

While stated as well in patch 4, prominently here too: To preempt the
question - if we weren't to do this (i.e. leave legacy-encoded SIMD
insns using eGPR-s alone), I'd raise the counter question of why these
insns are supported by APX then in the first place.

Besides corrections and extensions in patch 2, patch 3 is new in v2.

1: zap value-less Disp8MemShift from non-EVEX templates
2: APX: extend SSE2AVX coverage
3: APX: further extend SSE2AVX coverage
4: tidy <sse*> templates
