So if a test does not have any requirements we won't run it on each target, just once in general?

There are two things to consider:
- The unelaborated test is the same for all targets, so do we want to randomize it once for each target or randomize it once and use that for each target? If the latter, then we don't have to copy it. But I guess the earlier approach would be the more consistent one, right?
- Currently I assume that all tests for all targets will be run on the same system because there is no way to distinguish them after this pass. If we want to have targets for different systems in the same MLIR file, we'd need some scoping, add the target that the test specialized for as an attribute, or some other way to distinguish them. As long as we don't do that, we don't need to duplicate a test that has the same content.
I guess I will change it to be copied and independently randomized for each target, but leave point 2 for a future PR.

I don't really know whats best, what you had originally is probably good! We can revisit these points in the future easily enough.
