I don't think we need both the LLVM IR + VPlan tests for the scalable cases, either one is enough. My main concern is that we don't really use llvm-extract anywhere else in the llvm/test/transforms directory, and I'm not sure if this test case is special enough to warrant it. 

In any case splitting the files seems like the easiest way to avoid blocking #182595, we can always revisit the testing structure and format separately
