re PR other/63504 (Issues found by --enable-checking=valgrind) 

	PR other/63504
	* dwarf2out.c (add_AT_wide, mem_loc_descriptor, loc_descriptor):
	Use ggc_alloc<wide_int> instead of ggc_cleared_alloc<wide_int>.
	(attr_checksum, attr_checksum_ordered, hash_loc_operands): Checksum
	only get_full_len HOST_WIDE_INTs from get_val () array rather than
	all bits in *val_wide.
