	PR middle-end/31150
	* dse.c (struct store_info): Add const_rhs field.
	(clear_rhs_from_active_local_stores): Clear also const_rhs.
	(record_store): Try also cselib_expand_value_rtx to get a constant.

	* cselib.c (cselib_record_sets): If !cselib_record_memory and
	there is just one set from read-only MEM, look at REG_EQUAL or
	REG_EQUIV note.

	* dse.c (struct store_info): Add redundant_reason field.
	(record_store): When storing the same constant as has been
	stored by an earlier store, set redundant_reason field
	to the earlier store's insn_info_t.  Don't delete cannot_delete
	insns.
	(find_shift_sequence): Remove read_info argument, add read_mode
	and require_cst arguments.  Return early if require_cst and
	constant wouldn't be returned.
	(get_stored_val): New function.
	(replace_read): Use it.
	(scan_insn): Put even cannot_delete insns with exactly 1 store
	into active_local_stores.
	(dse_step1): Don't delete cannot_delete insns.  Remove redundant
	constant stores if contains_cselib_groups and earlier store storing
	the same value hasn't been eliminated.
	(dse_step6): Renamed to dse_step7.  New function.
