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.

Alexey Bataev 7f246e003a [SLP] Allow vectorization of reversed loads. 
Summary:
Reversed loads are handled as gathering. But we can just reshuffle
these values. Patch adds support for vectorization of reversed loads.

Alexey Bataev 9c5c103283 [SLP] Fix for PR32086: Count InsertElementInstr of the same elements as shuffle. 
Summary:
If the same value is going to be vectorized several times in the same
tree entry, this entry is considered to be a gather entry and cost of
this gather is counter as cost of InsertElementInstrs for each gathered
value. But we can consider these elements as ShuffleInstr with
SK_PermuteSingle shuffle kind.
