After thinking about this last night, i believe that this problem should
be solved at the machine description level, not by changing
auto-inc-dec.c.  Auto-inc-dec.c uses all of the standard interfaces to
keep from generating invalid rtl.  So it seems proper to have the md
level not allow the creation of this insn.
