[flang] Fix handling of space between # and name in preprocessor stringification

When preprocessing "# ARG" in function-like macro expansion,
the preprocessor needs to pop the previously-pushed '#' token
from the end of the resulting token sequence after detecting the
argument name.  The code to do this was just wrong in a couple of
ways.
