That's a good question. I based the current `@IR` verifications on the vector nodes checked in the original test, and the `test_*` functions that do not currently have `@IR` annotations are those that do not result in any of the vector operations part of the original test.

I additionally checked a few of these functions in IGV, and none of them resulted in any vector operations. I guess we can remove them altogether, unless they are actually supposed to generate vector operations.
