[jdk21u-dev] RFR: 8300148: Consider using a StoreStore barrier instead of Release barrier on ctor exit

[Aleksey Shipilev]

The backport is not clean because the hunk in `macro.cpp` does not apply to JDK 21, because it was added later with [JDK-8287061](https://bugs.openjdk.org/browse/JDK-8287061).

Additional testing:
 - [x] New benchmark improves
 - [x] New IR test passes
 - [x] Linux AArch64 server fastdebug, `all`
 - [x] Linux x86_64 server fastdebug, `all`
