If have just one non-undef scalar in the buildvector/gather node, we try to put it to be the very first element, which is profitable in most cases. Do the preliminary estimation, if this more profitable during graph rotation and do same for all elements, including extractelements. Differential Revision: https://reviews.llvm.org/D144689
