/* If the function appears to be frameless, check a couple of likely

Two common cases of this are missing symbols (i.e.
frame_func_unwind returns the wrong address or 0), and assembly
get_frame_func returns the wrong address or 0), and assembly
stubs which have a fast exit path but set up a frame on the slow
path.
