Hi @eme64 , 
I have extended IR test points to check functional correctness using Verify.checkEQ.
Created a follow-up JBS entry for scalar IR communing [https://bugs.openjdk.org/browse/JDK-8348134](https://bugs.openjdk.org/browse/JDK-8348134)
For now, I have assigned it to myself. Please feel free to re-assign it; I can help with the reviews. 

Please go ahead with test runs.

Best Regards,
Jatin
