<pre>This is obviously broken:
$ cat t.s
.intel_syntax
foo:
call dword ptr [foo]
$ llvm-mc t.s
.text
foo:
calll foo
Both 'foo' and '[foo]' get parsed as absolute memory X86Operands, and the
pcrel32 variants of 'call' match absolute memory operands. Therefore we have
ambiguity. The gas-style assembler looks for an optional '*' token to
disambiguate.
