Addressed feedback from Michael and Elena.

- Updated comment.
- Added two new test cases. In the first, we have a loop-varying GEP that is stored to memory, and in the second, we have a loop-invariant GEP that is stored to memory. In the first, we create a vector GEP, and in the second, we recreate the scalar GEP and then broadcast it.
