[BZ #15897] dlfcn: do not mark dlopen/dlclose as leaf functions
Since the dlopen funcs might invoke a constructor that calls a func that is in the same compilation unit as the caller, we cannot mark them as leaf funcs. Similarly, dlclose might invoke a destructor that calls a func that is in the same compilation unit as the caller.
