rewrite check for bad memory in debug_can_save_memory
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-01-15 Ben Wing <ben@xemacs.org>
* emacs.c:
* emacs.c (debug_can_access_memory):
When checking for bad memory, we need to read all bytes from memory;
try even harder to avoid the possibility that a super-optimizing
compiler will optimize away the memory reads.
