[PATCH] D115052: [Passes] Only run extra vector passes if loops have been vectorized.

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

It would be good to mimic what the module equivalence check does
(when no changes were reported, the module should not have been changed),
and e.g. when in EXPENSIVE_CHECKS mode, if we weren't going to run those
extra vectorization passes because we predicted they wouldn't do anything,
to still run them, and check that they actually didn't do anything.
