    cfg: Dump goto_locus if -fdump-*-*-blocks-details
    
    When debugging the PR104589 issue, I've run into a problem that
    goto_locus doesn't show up in the logs, so it wasn't clear if
    the bug hasn't been introduced far earlier just by divergence
    in goto_locus of some edge.

            * cfg.cc (dump_edge_info): Dump goto_locus if present.
