Re-committing after r311325 fixed an unintentional use of '#' comments in
clang.
The '#' token is not a comment for all targets (on ARM and AArch64 it marks an
immediate operand), so we shouldn't treat it as such.
Comments are already converted to AsmToken::EndOfStatement by
AsmLexer::LexLineComment, so this check was unnecessary.
