    tree-optimization/106866 - avoid dead abnormal edges from DCE

    When DCE clears cfun->calls_setjmp then suddenly we don't need
    any abnormal call edges anymore.  The following makes sure to
    prune them which otherwise can confuse other passes.

            * tree-ssa-dce.cc (eliminate_unnecessary_stmts): When
            we changed cfun->calls_setjmp make sure to purge all
            abnormal call edges.
