    tree-optimization/110443 - prevent SLP splat of gathers

    The following prevents non-grouped load SLP in case the element
    to splat is from a gather operation.  While it should be possible
    to support this it is not similar to the single element interleaving
    case I was trying to mimic here.

            PR tree-optimization/110443
            * tree-vect-slp.cc (vect_build_slp_tree_1): Reject non-grouped
            gather loads.

            * gcc.dg/torture/pr110443.c: New testcase.=
