RKSimon added a comment.

@ABataev I think as a patch adding upper subvector extraction support for X86 getScalarizationOverhead this is ready now. I'd prefer to wait to a later patch to add specific getExtractWithExtendCost handling to getScalarizationOverhead once I know exactly how I'm going to implement it in SLP.
