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. From-SVN: r172785
