    vect: Variable lane indices in vectorizable_slp_permutation_1 [PR116583]

    The main patch for PR116583 needs to create variable indices into
    an input vector.  This pre-patch changes the types to allow that.

    There is no pretty-print format for poly_uint64 because of issues
    with passing C++ objects through "...".

            poly_uint64 for scalar lane indices.
