Description
Virtual Threads are not fully implemented on x86_32. The feature is guarded with `--enable-preview`. But there is some VM code that is executed unconditionally anyway, crashing the VM on some tests. This improves the x86_32 code to the point that tests without `--enable-preview` run successfully. This adds the scaffolding for full implementation too.
