fwprop: invoke change_is_worthwhile to judge if a replacement is worthwhile
gcc/
* fwprop.cc (try_fwprop_subst_pattern): Invoke change_is_worthwhile
to judge if a replacement is worthwhile. Remove single_set check
and add is_debug_insn check.
* recog.cc (swap_change): Invalidate recog_data when the cached INSN
is swapped out.
* rtl-ssa/changes.cc (rtl_ssa::changes_are_worthwhile): Check if the
insn cost of new rtl is unknown and fail the replacement.
