    tree-optimization/110630 - enhance SLP permute support

    The following enhances the existing lowpart extraction support for
    SLP VEC_PERM nodes to cover all vector aligned extractions.  This
    allows the existing bb-slp-pr95839.c testcase to be vectorized
    with mips -mpaired-single and the new bb-slp-pr95839-3.c testcase
    with SSE2.

            PR tree-optimization/110630
            * tree-vect-slp.cc (vect_add_slp_permutation): New
            offset parameter, honor that for the extract code generation.
            (vectorizable_slp_permutation_1): Handle offsetted identities.

            * gcc.dg/vect/bb-slp-pr95839.c: Make stricter.
            * gcc.dg/vect/bb-slp-pr95839-3.c: New variant testcase.=
