  [LV] Consolidate shouldOptimizeForSize and remove unused BFI/PSI. NFC (#168697)

#158690 plans on passing BFI as a lazy lambda to avoid computing
BlockFrequencyInfo when not needed.

In preparation for that, this PR removes BFI and PSI from some
constructors that aren't used. It also consolidates the two calls to
llvm::shouldOptimizeForSize so that the result is computed once and
passed where needed.

This also renames OptForSize in LoopVectorizationLegality to clarify
that it's to prevent runtime SCEV checks, see
