Fix a couple of bugs:

1. When we accept "#garbage" in asm-with-cpp mode, change the token kind
of the # to unknown so that the preprocessor won't try to process it as

2. Fix macro definition extents processing to handle #foo at the end of a
macro to say the definition ends with the foo, not the #.
