		PR rtl-optimization/44194
		* calls.c (expand_call): In the PARALLEL case, copy the return value
		into pseudos instead of spilling it onto the stack.
		* emit-rtl.c (adjust_address_1): Rename ADJUST into ADJUST_ADDRESS and
		add new ADJUST_OBJECT parameter.
		If ADJUST_OBJECT is set, drop the underlying object if it cannot be
		proved that the adjusted memory access is still within its bounds.
		(adjust_automodify_address_1): Adjust call to adjust_address_1.
		(widen_memory_access): Likewise.
		* expmed.c (store_bit_field_1): Call adjust_bitfield_address instead
		of adjust_address.  Do not drop the underlying object of a MEM.
		(store_fixed_bit_field): Likewise.
		(extract_bit_field_1): Likewise.  Fix oversight in recursion.
		(extract_fixed_bit_field): Likewise.
		* expr.h (adjust_address_1): Adjust prototype.
		(adjust_address): Adjust call to adjust_address_1.
		(adjust_address_nv): Likewise.
		(adjust_bitfield_address): New macro.
		(adjust_bitfield_address_nv): Likewise.
		* expr.c (expand_assignment): Handle a PARALLEL in more cases.
		(store_expr): Likewise.
		(store_field): Likewise.
	
		* dse.c: Fix typos in the head comment.
