@amanasifkhalid, PTAL if it is a codegen issue.

I've run the failing tests locally for a few hours, and they have yet to fail. I suspect there's some interleaving of threads that causes an AV in ILC. The stress configuration doesn't look all that meaningful: One test failed with only GC stress, and the other tests failed with only LSRA stress.

This hasn't hit in the last few runs. Removing blocking-optional tag.
