  Changed paths:
    M llvm/lib/Target/X86/AsmParser/X86AsmParser.cpp
    M llvm/test/MC/X86/encoder-fail.s

  Log Message:
  -----------
  [X86] Error on using h-registers with REX prefix in the assembler instead of leaving it to a fatal error in the encoder.

Using a fatal error is bad for user experience.
