kmclaughlin added a comment.

- Add store instructions to the `Uniforms` list in collectLoopUniforms, instead of the worklist. Added more comments to clarify that instructions in `Uniforms` may demand the first or last lane.
- Moved the new tests in sve-uniform-store.ll into sve-inv-store.ll.
- Removed the CHECK lines from `middle.block` from `@inv_store_i16`
