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.
