> Currently, parallel iv optimization only happens in an int counted loop with \
> int-typed parallel iv's. This PR adds support for long-typed iv to be optimized.  
> Additionally, this ticket contributes to the resolution of \
> [JDK-8275913](https://bugs.openjdk.org/browse/JDK-8275913). Meanwhile, I'm working \
> on adding support for parallel IV replacement for long counted loops which will \
