Using leaf_function_p in a backend is dangerous as it incorrectly returns
false if it is called while in a sequence (for example during prolog/epilog
generation). Replace all uses with crtl->is_leaf as this is now initialized
early enough in ira.c. This typically causes no code generation differences
unless there was a bug due to leaf_function_p returning the wrong value.
