[PATCH] D109444: [LV][WIP] Don't vectorize if we can prove RT + vector cost >= scalar cost (alt. version)

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Suppose D109368 <https://reviews.llvm.org/D109368> lands first.
Is this particular patch an NFC change, or a functional-one?
What i'm asking is, where does this matter?
Can you add tests where the cost of the checks will be radically different for different VF's?
