046957830e remove useless if-before-free tests 
Change "if (E) free (E);" to "free (E);" everywhere except in the
libgo/, intl/, zlib/ and classpath/ directories.
Also transform equivalent variants like
"if (E != NULL) free (E);" and allow an extra cast on the
argument to free.  Otherwise, the tested and freed "E"
expressions must be identical, modulo white space.

Do that by running this command:
  perl -pi -e    's/\bgfc_free ?\(/free (/' \
    $(git grep -El '\bgfc_free ?\(')
which also corrects the few uses that lacked a space between
the function name and the open parenthesis.
Manually undo the change to the function definition itself
