The test is already marked as GCStressIncompatible, so why is it running? This looks introduced by #92029. @trylek can you figure out how to disable it again so that GCStress isn't red?

[jakobbotsch]

Also cc @markples, I seem to recall him having some similar issues around GCStress when doing the JIT test merging. Not sure how we ended up resolving it.

[markples]

This test needs to have RequiresProcessIsolation set. The merged infrastructure doesn't handle GCStressIncompatible, so we need to go back to the cmd/sh logic for now. @trylek Can you please check the steps that you used to convert this directory to see if there are any others like this? (Did ILTransform miss it, or was another technique used here?)
