[13] RFR(T): 8224957: C2 compilation fails with assert: Bad graph detected in build_loop_late

[Tobias Hartmann]

Roland, Vladimir, thanks for the reviews!

Unfortunately, testing revealed another spurious crash (non-schedulable graph) that only happens
with my patch. I suspect that this issue is unrelated but only triggers due to the changes to
Node::dominates.

Since I need more time to investigate and due to concerns about other potential issues that might be
triggered by this fix, I've decided to disable AggressiveUnboxing for JDK 13. I've filed 8228710 [1]
and will send a RFR soon.

Best regards,
Tobias
