Not sure, but read_memory_unsigned_integer() might not be safe,
because of the possibility of inserted breakpoints.  The safe
alternative is safe_frame_unwind_memory().  But of course that means
that in_function_epilogue_p should really be changed such that it
accepts a `struct frame *' as an argument.
