[PATCH 00/12] x86: disassembler fixes and some consolidation

[Jan Beulich]

This has started by me noticing that OP_G() handles "bytemode"
values it never gets passed. But here you go - I've found a
couple of bugs as I was going, and extended / better ways of
cleaning up some code. But the duplication of register printing
was something that has been puzzling me for a while, not the
least because with about every other ISA extension two places
have been getting touched when just one should have done.

01: drop OP_Mask()
02: correct VCVT{,U}SI2SD rounding mode handling
03: generalize OP_G()'s EVEX.R' handling
04: properly bounds-check %bnd<N> in OP_G()
05: fold duplicate register printing code
06: fold duplicate code in MOVSXD_Fixup()
07: correct EVEX.V' handling outside of 64-bit mode
08: drop vex_mode and vex_scalar_mode
09: fold duplicate vector register printing code
10: drop xmm_m{b,w,d,q}_mode
11: drop vex_scalar_w_dq_mode
12: drop dq{b,d}_mode
