    c++: computed goto from catch block [PR81438]

    As with 37722, we don't clean up the exception object if a computed goto
    leaves a catch block, but we can warn about that.

            PR c++/81438

    gcc/cp/ChangeLog:

            * decl.cc (poplevel_named_label_1): Handle leaving catch.
            (check_previous_goto_1): Likewise.
            (check_goto_1): Likewise.

    gcc/testsuite/ChangeLog:

            * g++.dg/ext/label15.C: Require indirect_jumps.
            * g++.dg/ext/label16.C: New test.
