This program spends 90% of its time in asan::FakeStack::GC. I think we are causing quadratic work in ASAN because it is accumulating shadow frames because our throws don't inform ASAN that we did something longjmp-like. We probably need to hook into longjmp like we did for TSAN in https://dart-review.googlesource.com/c/sdk/+/222300.
