Test failures: stackoverflowtester

[BruceForstall]

This new test (added in #35667) is failing many legs in the AzDO jitstress pipeline.

This is happening for Windows and Linux, for all architectures. I don't think it's every run, and I couldn't reproduce a failure on Windows x64 Checked on a local machine.

(Note that the jitstress pipeline is actually running correctly, whereas the runtime and "runtime-coreclr outerloop" pipelines are only running a small subset of the tests they are supposed to)

I'm looking into it.

The problem is that System.Threading.ThreadHelper.ThreadStart is missing from the stack trace. Looks like the System.Threading.ExecutionContext.RunInternal got tail-called by it and so the ThreadStart frame is not on the stack.
