re PR target/25005 (ICE in extract_constrain_insn_cached, at recog.c:2002) · cb292345

	PR target/25005
	* regrename.c (replace_oldest_value_reg): Use validate_change with
	IN_GROUP set to 1 instead of doing direct modifications.
	(copyprop_hardreg_forward_1): Likewise.  If any replace_oldest_*
	replacements have been performed on an instruction, use
	apply_change_group ().

	* g++.dg/opt/pr25005.C: New test.
