I saw it in Full LTO but suppose we have a similar problem in ThinLTO. SLP vectorizer at compile-time tries to vectorize using small vectors at it may affect other optimizations at link time (e.g. after inlining we may try to vectorize using large vector sizes etc.). This is just a preliminary attempt to see how can we fix this early optimization in SLP.
