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

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.

Florian Hahn e32ff4b28a [InstCombine] Do not fold scalar ops over select with vector condition. 
If OtherOpT or OtherOpF have scalar types and the condition is a vector,

John Brawn 2867bd72c0 [InstCombine] Make foldSelectOpOp able to handle two-operand getelementptr 
Three (or more) operand getelementptrs could plausibly also be handled, but
handling only two-operand fits in easily with the existing BinaryOperator
handling.
