[PATCH] MC: provide the ability to disable assembly parsing

[Renato Golin]

  Hi Saleem,

  This would work, but my thought was something that would actually run the parser, and only if it failed AND we want to report errors, we abort.

  ex:

    int Res = Parser->Run(...);

    if (Res && !ValidateInlineASMSyntax)
      OutStreamer.EmitRawText(Str);

    else if (Res && !HasDiagHandler)
      report_fatal_error()

    emitInlineAsmEnd(STIOrig, STI.get())

  That, of course, assuming the Parser won't print anything unless the whole thing succeeds, which I'm not certain of.

  Also, I think this option should be false by default on -S output, and only changed if -Wno-bad-inline-asm or equivalent.

  cheers,
  --renato
