Jan Beulich 71760cf0fe x86emul: work around gcc11 bug in SIMD tests 
Gcc11 looks to have trouble with conditional expressions used with
vector operands: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104497.
Replace two instances causing SEGV there in certain cases.

Jan Beulich 7d569b8480 x86emul: support AVX512F scatter insns 
This completes support of AVX512F in the insn emulator.

Note that in the test harness there's a little bit of trickery needed to
get around the not fully consistent naming of AVX512VL gather and
scatter compiler built-ins. To suppress expansion of the "di" and "si"
tokens they get constructed by token concatenation in BS(), which is
different from BG().
