In HLSL, there are three (TODO: ??) dimensions of clip and cull distance values: * The semantic's value N, ala SV_ClipDistanceN. * The array demension, if the value is an array. * The vector element, if the value is a vector or array of vectors. In SPIR-V, clip and cull distance are arrays of scalar floats, always. This PR currently ignores the semantic N axis, and handles the other two axes by sequentially copying each vector element of each array member into sequential floats in the output array. Fixes: #946
