PR debug/48163
	* var-tracking.c (prepare_call_arguments): If CALL target
	is a non-SYMBOL_REF CONSTANT_P, just add that into the list as
	pc instead of looking it up using cselib_lookup and use
	Pmode for it if x has VOIDmode.
	* dwarf2out.c (gen_subprogram_die): If also both first and
	second CONCAT arguments are VOIDmode, use mode of CONCAT itself.
