[llvm] [LoopVectorize] Improve Vectorization of Low Trip Count Loops (PR #195823)

[Florian Hahn via llvm-commits]

The threshold looks fine to me, thanks. Please make sure we have a dedicated test where we do not use the new style of vectorization due to the size of the loop being < the threshold and maybe one that has enough instructions to exceed the default threshold
