[PATCH] Fix dwarf2out wide-int issues (PR other/63504)

Hi! Despite the cleared_ part, the attr.dw_attr_val.v.val_wide = ggc_cleared_alloc (); *attr.dw_attr_val.v.val_wide = w; etc. sequences put in there uninitialized bits (array elements beyond get_len (), and perhaps structure padding), as it constructs a temporary and then assigns it to *val_wide.
