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.

Sanjay Patel 0d66010454 [Reassociate] don't name values "tmp"; NFCI
The toxic stew of created values named 'tmp' and tests that already have
values named 'tmp' and CHECK lines looking for values named 'tmp' causes
bad things to happen in our test line auto-generation scripts because it
wants to use 'TMP' as a prefix for unnamed values. Use less 'tmp' to 
avoid that.

Owen Anderson 2de9f545aa Add intermediate subtract instructions to reassociation worklist.
We sometimes create intermediate subtract instructions during
reassociation.  Adding these to the worklist to revisit exposes many
additional reassociation opportunities.

Patch by Aditya Nandakumar.

Chad Rosier 11ab941644 [Reassociation] Add support for reassociation with unsafe algebra.
Vector instructions are (still) not supported for either integer or floating
point.  Hopefully, that work will be landed shortly.
