Eric Christopher cee313d288 Revert "Temporarily Revert "Add basic loop fusion pass."" 
The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

Eric Christopher 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.

Ivan A. Kosarev f03f579d1d [Transforms] Propagate new-format TBAA tags on simplification of memory-transfer intrinsics 
With this patch in place, when a new-format TBAA tag is available
for a memory-transfer intrinsic call, we prefer propagating that
new-format tag. Otherwise, we fallback to the old approach where
we try to construct a proper TBAA access tag from 'tbaa.struct'
metadata.
