vdmitrie added a comment.

Updated getScalarizationOverhead to use new TTI API for chained inserts/extracts.
This reduced cost overestimates in many cases brought with https://reviews.llvm.org/D74976.
Cost model tests adjusted to reflect that.
Tests Transforms/SLPVectorizer/X86/resched.ll and Transforms/LoopVectorize/X86/strided_load_cost.ll reverted to state prior to D74976 <https://reviews.llvm.org/D74976>.
