    middle-end/104450 - ISEL and non-call EH

    The following avoids merging a vector compare with EH with a
    VEC_COND_EXPR.  We should be able to do fallback expansion and if
    we really are for the optimization we need quite some shuffling
    to arrange for the proper EH redirection in all cases, IMHO not
    worth it.
