RFR: 8291809: Convert compiler/c2/cr7200264/TestSSE2IntVect.java to IR verification test [v7]

[Daniel Lundén]

> This changeset translates the tests in `compiler/c2/cr7200264/` to use the IR verification framework.
> 
> The proposed translation, to the extent possible, attempts to preserve the semantics of the original test. A major difference is that the IR checks are now local (for every `test_*` method) instead of global. The execution time of the new test is comparable to the old test.
> 
> Testing:
> - [GitHub Actions](https://github.com/dlunde/jdk/actions/runs/7671780152)
> - Ran the new translated tests within all tier1 through tier10 contexts on windows-x64, linux-x64, linux-aarch64, macosx-x64, and macosx-aarch64.
> - Tested that manually adding `-XX:LoopUnrollLimit=0` to the test framework flags caused the translated tests to fail. Note: it is, however, no longer possible to break the test by passing `-XX:LoopUnrollLimit=0` on the command line.
