re PR bootstrap/44255 (gcc-4.6-20100522 bootstrap comparison failure on sparc64 and arm)
PR bootstrap/44255
* combine.c (struct rtx_subst_pair): Define unconditionally.
(propagate_for_debug_subst): Likewise. If not AUTO_INC_DEC,
copy_rtx pair->to instead of cleanup_auto_inc_dec it.
Call make_compound_operation on pair->to.
(propagate_for_debug): Don't call make_compound_operation here.
Always use simplify_replace_fn_rtx.
