[Florian Hahn via Phabricator via llvm-commits]

Split out moving various functions to LoopVectorizationCostModel to D61638 <https://reviews.llvm.org/D61638>.

Hoisted needsExtract to do the check if we need to extract/scalarize an operand
to LoopVectorizationCostModel and extend it to check for loop invariant operands.
