xdiff: use BUG(...), not xdl_bug(...)
The xdl_bug() function was introduced in e8adf23d1e (xdl_change_compact(): introduce the concept of a change group, 2016-08-22), let's use our usual BUG() function instead. We'll now have meaningful line numbers if we encounter bugs in xdiff, and less code duplication.
