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

Will be re-reverting again.

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.

1440107821 [InstSimplify] fold select (fcmp X, Y), X, Y 
This is NFCI for InstCombine because it calls InstSimplify, 
so I left the tests for this transform there. As noted in
the code comment, we can allow this fold more often by using
FMF and/or value tracking.

72c2d355b7 [InstSimplify] add tests for select+fcmp; NFC 
These are translated from InstCombine's test file with the same name.
We should move the transform from InstCombine to InstSimplify.
