Several things which I think should be done:
1. merge and rebase with latest riscv-port branch to make the conflicts resolved; 
2. add necessary fixes like [JDK-8295926](https://bugs.openjdk.org/browse/JDK-8295926) and [JDK-8293100](https://bugs.openjdk.org/browse/JDK-8293100) which were mentioned previously on this PR; 
3. remove unnecessary fixes like [JDK-8247533](https://bugs.openjdk.org/browse/JDK-8247533); 
4. Related this PR with JBS issues contained.
