Detailed Description

This pass collects the instructions that can become vectorization "seeds", like stores to consecutive memory addresses.

It then goes over the collected seeds, slicing them into appropriately sized chunks, creating a Region with the seed slice as the Auxiliary vector and runs the region pass pipeline.
