Herald added a project: LLVM.

This makes the following program build with -masm=intel:

  int foo(int count) {
    asm goto ("dec %0; jb %l[stop]" : "+r" (count) : : : stop);
    return count;
  stop:
    return 0;
  }

It's also is another step towards merging EmitGCCInlineAsmStr() and
EmitMSInlineAsmStr().
