[PATCH] D74185: Revert the revert of vectorization commits

[George Karpenkov via Phabricator via llvm-commits]

@ABataev  Please check out the runnable reproducer above. It clearly demonstrates a miscompile: if the pass is correct, same IR input should give identical output (barring undefined behavior, but we use sanitizers to check for that).

> Also, reverting is not productive, better to try to find a proper fix.

Miscompiles should be reverted just based on incorrect behavior.
