[PATCH] D48214: [SLPVectorizer] Recognise non uniform power of 2 constants

Since https://reviews.llvm.org/D46637 we are better at handling uniform/non-uniform constant Pow2 detection; this patch tweaks the SLP argument handling to support them.

As SLP works with arrays of values I don't think we can easily use the pattern match helpers here.
