[PATCH] D14829: [SLP] Vectorize gather-like idioms ending at non-consecutive loads.

Ayal added a comment.

Functionally this looks fine to me, thanks! I have no further comments. Nadav or Hal should formally LGTMize it though.

Cool. It would be good to record other known gains (povray?). This could be useful, e.g., if one attempts to recognize such patterns starting at consecutive loads going downwards, rather than arbitrary independent GEPs going upwards.
