Addressed Gil's comments
- Added a comment to the test indicating that the functionality being tested is not AArch64-specific.
I had originally intended to make the test target-independent using the force-target-instruction-cost flag to set the instruction costs. But this flag resets the costs after calculating the scalarization overhead and scaling the costs by block probability. So that doesn't help. I'm not sure of the best way to go about checking multiple targets without excessive duplication, so I went with adding the suggested "not AArch64-specific" comment for now. Thanks!
