I've drafted a CSR for this. Please review:

https://bugs.openjdk.java.net/browse/JDK-8284377

I haven't yet reviewed all the call sites in detail, but I'll continue doing so. You're ambitious! But the number of call site errors that are fixed by this new API is quite high, so doing this is worthwhile.

I don't think we need this benchmark in this PR.

Note, for future reference, benchmarks are located in the `test/micro` directory and not with the main regression suite in `test/jdk`.
