This patch is part of a series of patches that migrate integer
instruction costs to use InstructionCost. I've changed
selectVectorizationFactor to use a different algorithm for
comparing costs, since now the costs are integer based. I
believe we get the same result as we had previously with
float values.

See this patch for the introduction of the type: https://reviews.llvm.org/D91174
