	PR debug/41404
	PR debug/41353
	* cfgexpand.c (expand_debug_expr) <case STRING_CST>: Don't create
	CONST_STRING if STRING_CST contains embedded '\0's or doesn't end with
	'\0'.
	(expand_debug_expr) <case VAR_DECL>: For TREE_STATIC !DECL_EXTERNAL
	vars use DECL_RTL with resetting it back to NULL afterwards.
	* dwarf2out.c (same_dw_val_p): For dw_val_class_addr compare with
	rtx_equal_p instead of asserting it is a SYMBOL_REF.
	(value_format): For dw_val_class_addr only use DW_FORM_addr if
	the attribute type allows it, otherwise use DW_FORM_dataN.
	(mem_loc_descriptor): Handle CONST_STRING.
	(add_const_value_attribute): Handle CONST_STRING using add_AT_addr.
	Handle MEM with CONST_STRING address using add_AT_string.
	(rtl_for_decl_init): Return MEM with CONST_STRING address instead of
	CONST_STRING for const arrays initialized with a string literal.
	(resolve_one_addr, resolve_addr_in_expr, resolve_addr): New functions.
	(dwarf2out_finish): Call resolve_addr.

	* gcc.dg/guality/pr41404-1.c: New test.
