So there are crashes in our tests with this pr applied.
E.g. `make test TEST=runtime/CommandLine/OptionsValidation/TestOptionsWithRangesDynamic.java` crashes always. To me it seems that the issue is unrelated to virtual threads. It has to be caused by relativization of `top_frame_sp`
Unfortunately I cannot look into it since I'm actually on vacation. @TheRealMDoerr might want to look into it. He's coming back from vacation in a couple of days.
