These tests revolve around checking that the implied offsets fit the simm12 immediates. When they do, the offsets can be folded into the loads/stores, and therefore they should have zero cost.
The patch adds vector tests, despite the RISC-V backend currently not targetting any vector units. That was a borderline decision. Since we can compile IR vector instructions to scalar native ones, I felt including the vector tests made sense. This way we also have the infrastructure already in place for when we decide to add support for vector extensions.
