Rebased, Removed SLP parameter MinVecNodes. Added estimations of a good tree reduction 1) if the tree contained some real operations like binary, arithmetical, calls which were proposed to vectorize then we don't want to reduce this tree to just load and store operations in vectorized form. 2) if the tree doesn't have any real operations like binary, arithmetical... then we have to make sure that at least the root node and the next node to root are going to be vectorized.
