[jdk21u-dev] RFR: 8327990: [macosx-aarch64] Various tests fail with -XX:+AssertWXAtThreadSync

[Richard Reingruber]

I would like to backport https://github.com/openjdk/jdk22u/commit/0c572566963be7f941228deda2691ce2fc456c15 to jdk 21 to get clean testing with -XX:+AssertWXAtThreadSync and avoid crashes because the VM is entered with the wrong WXState. The latter is very unlikely nevertheless aiming for clean tests with -XX:+AssertWXAtThreadSync will help to reduce the probability that users are affected by regressions in this area.

Testing:

I've verified every added WXState change if it is actually required.

The fix passed our CI testing with AssertWXAtThreadSync enabled: JTReg tests: tier1-4 of hotspot and jdk. All of Langtools and jaxp. JCK, SPECjvm2008, SPECjbb2015, Renaissance Suite, and SAP specific tests.
