	PR target/31850
	* rtl.h (push_to_sequence2): New.
	* emit-rtl.c (push_to_sequence2): New.
	* function.c (assign_parm_data_all): Add new fields.
	(assign_parm_setup_block): Call push_to_sequence2 instead of 
	push_to_sequence.
	(assign_parm_setup_reg): Ditto.
	(assign_parm_setup_stack): Ditto.
	(assign_parms_unsplit_complex): Ditto.
