    tree-optimization/108076 - if-conversion and forced labels

    When doing if-conversion we simply throw away labels without checking
    whether they are possibly targets of non-local gotos or have their
    address taken.  The following rectifies this and refuses to if-convert
    such loops.

            PR tree-optimization/108076
            * tree-if-conv.c (if_convertible_loop_p_1): Reject blocks
            with non-local or forced labels that we later remove
            labels from.

            * gcc.dg/torture/pr108076.c: New testcase.
