Log:

    * 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.
