[PATCH] D104809: [SLPVectorizer] Fix crash in vectorizeChainsInBlock for scalable vector.

[Caroline via Phabricator via llvm-commits]

@ABataev I try to follow your suggestion. 
I could not find a test that could fail without a extract instruction. 
So I followed your suggestion.
The previous one implemented was more generic. 
What is done in getEntryCost is what you had in mind for the cost when it is an extract instruction?
