The backtrace offline code uses these error codes to diagnose errors. In addtion, I've had cases where seeing these errors would help diagnose failures. This also allows us to add a few features to indicate why an unwind terminated (such as max frames exceeded). Bug: 65682279 Test: Updated unit tests pass.
