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] Support vector splats in transformZExtICmp
...
This patch adds splat support to transformZExtICmp. The test cases are vector versions of tests that failed when commenting out parts of the existing scalar code.
One test didn't vectorize optimize properly due to another bug so a TODO has been added.

[InstCombine] try to canonicalize xor-of-icmps to and-of-icmps
...
We have a large portfolio of folds for and-of-icmps and or-of-icmps in InstSimplify and InstCombine,
but hardly anything for xor-of-icmps. Rather than trying to rethink and translate all of those folds,
we can use the truth table definition of xor:
X ^ Y --> (X | Y) & !(X & Y)
...to see if we can convert the xor to and/or and then use the existing folds.

[InstCombine] handle icmp i1 X, C early to avoid creating an unknown pattern

The missing optimization for xor-of-icmps still needs to be added, but by
being more efficient (not generating unnecessary logic ops with constants)
we avoid the bug.
