RFR: Merge panama [v2]

[Jorn Vernee]

> Merge panama branch into jdk22 branch, to pull in all the latest changes for jdk22
> 
> This PR also contains a small fix in `test/jtreg/generator/clinitCycles/libClinitGlobal.c`. This file was including a header using `#include <...>` which doesn't work on some versions of GCC. `<>` should be used for system headers. I've switched the test to using `#include "..."` instead, which works.
