[jdk17u-dev] RFR: 8302736: Major performance regression in Math.log on aarch64

[Goetz Lindenmaier]

I backport this for parity with 17.0.9-oracle.

I resolved runtime.cpp because the comment in the context 
differs.
I omitted the change to continuationFreezeThaw.cpp.
This file is not in 17. It contains loom code, loom is not in 17.
