    tree-optimization/111082 - bogus promoted min

    vectorize_slp_instance_root_stmt promotes operations with undefined
    overflow to unsigned arithmetic but fails to consider operations
    that do not overflow like MIN which it turned into MIN with wrong
    signedness and in the case of the PR an unsupported operation.
    The following rectifies this.

            PR tree-optimization/111082
            * tree-vect-slp.cc (vectorize_slp_instance_root_stmt): Only
            pun operations that can overflow.

            * gcc.dg/pr111082.c: New testcase.=
