The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

a863435128 Temporarily Revert "Add basic loop fusion pass." 
As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

ba5acbc4fe [LV] Prevent interleaving if computeMaxVF returned None. 
As discussed in D57382, interleaving should be avoided if computeMaxVF
returns None, same as we currently do for vectorization.
