[x86][AVX512][FEAT] Memory broadcasting suffixes ({1to8}, {1to16}) support for x86 assembler.

[Bader, Aleksey A]

Only one minor comment from my side:

+  bool ErrorAndEatStatement(SMLoc L, const Twine &Msg,
+          ArrayRef<SMRange> Ranges = None,
+          bool MatchingInlineAsm = false) {

Last two arguments seem to be unnecessary for this function.

+      Parser.eatToEndOfStatement();
+      return Parser.Error(L, Msg);
+  }
+

Subject: [x86][AVX512][FEAT] Memory broadcasting suffixes ({1to8}, {1to16}) support for x86 assembler.

Please review my patch.

This patch:

  *   Makes x86 assembler (llvm-mc) recognize and parse memory broadcasting primitives from AVX512: {1to8} and {1to16}.
  *   Makes x86 assembler accept both Intel- and AT&T-styled AVX512 operands primitives. Affects {1to<NUM>}, {%k<NUM>} and {z}.
  *   Adds simple tests for {1to8} and {1to16} parsing.
  *   Slightly clean-ups X86AsmParser.cpp.
