Revert "Temporarily Revert "Add basic loop fusion pass.""

The reversion apparently deleted the test/Transforms directory.
Will be re-reverting again.

Temporarily Revert "Add basic loop fusion pass."
...
As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

[InstCombine] allow not+sub fold for arbitrary vector constants
...
The fold was implemented for the general case but use-limitation,
but the later constant version which didn't check uses was only
matching splat constants.

[InstCombine] fix/add tests for icmp with not ops; NFC

The existing test was not minimal, and there was no coverage
for the variants with a constant or vector types.

[InstCombine] add folds for not-of-shift-right
...
This is another step towards getting rid of dyn_castNotVal,
so we can recommit:
https://reviews.llvm.org/rL300977
As the tests show, we were missing the lshr case for constants
and both ashr/lshr vector splat folds. The ashr case with constant
was being performed inefficiently in 2 steps. It's also possible
there was a latent bug in that case because we can't do that fold
if the constant is positive:
