> These tests would be more idiomatic, precise, and possibly even faster if the IR verification was applied to each vectorization method (`test_sum`, `test_addc`, etc.) separately, instead of doing it as a bulk check over the entire `TestIntVect::testInner()`. This can be achieved by using `applyIfCPUFeature` annotations in the IR checks, similarly to e.g. `test/hotspot/jtreg/compiler/loopopts/superword/RedTest_int.java`. I recognize this limitation is pre-existing, but this issue seems a good place to address it.

I have now pushed a revised version (and updated the PR description). Please have a look when you have some spare time @robcasloz.
