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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@172785 138bc75d-0d04-0410-961f-82ee72b054a4
