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

Will be re-reverting again.

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.

Michael Kuperstein 5185b7dde3 [LV] Remove triples from target-independent vectorizer tests. NFC.
Vectorizer tests in the target-independent directory should not have a target
triple. If a test really needs to query a specific backend, it belongs in the
right target subdirectory (which "REQUIRES" the right backend). Otherwise, it
should not specify a triple.

Elena Demikhovsky 4c58b2761a Fixed consecutive memory access detection in Loop Vectorizer.
It did not handle correctly cases without GEP.

The following loop wasn't vectorized:

for (int i=0; i<len; i++)

  *to++ = *from++;

I use getPtrStride() to find Stride for memory access and return 0 is the Stride is not 1 or -1.
