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

@anemet In SelectionDAG we can use the memory order chains, and don't have to scan the whole basic block for loads/stores. This is very efficient, and is already used by the load-store merger in SelectionDAG.

I don't think that with the proposed patch we are very likely to catch patterns that cross basic blocks/loops. Can you show examples of real code that we do catch?
