Hi,

* Finished a presentation for NEON forum. Revital and Richard kindly agreed to take a look and gave me some valuable comments. Thanks!

* widen-shifts: - While preparing the presentation I found some room for improvement in the pattern detection, so I implemented it. It gave additional 13% to rgb24tobgr16. - Ramana suggested a solution on how to check the constant operand of vshll. Testing these two things on ARM.

* SLP improvements: - Implemented a patch that swaps operands if necessary to make the operations isomorphic, and supports loads with different offsets. Testing it now. - The three relevant libav loops now get vectorized giving 42%-57% speedup.

Next week holidays: half days Sunday-Wednesday and Thursday.
