	* trans-expr.c (gfc_conv_expr_op): Use zero constant
	that matches the lse type.
	(gfc_trans_string_copy): Use sizetype zero constant.
	* intrinsic.c (add_functions): The sizeof intrinsic has
	index type result.
	* trans-types.c (gfc_get_dtype): Convert size to index
	type before shifting.
	* trans-array.c (gfc_trans_array_constructor_value): Use
	index type for offset computation.
	* trans-intrinsic.c (gfc_conv_associated): Use correct type
	for zero constant.
