Sorry for only bringing it up now, but @tkrodriguez just observed that several of the places that test `TraceDeoptimization` aren't included in a `PRODUCT` build. In particular, [here](https://github.com/openjdk/jdk/blob/master/src/hotspot/share/runtime/vframeArray.cpp#L443), [here](https://github.com/openjdk/jdk/blob/master/src/hotspot/share/runtime/deoptimization.cpp#L265), and [here](https://github.com/openjdk/jdk/blob/master/src/hotspot/share/runtime/deoptimization.cpp#L731). Without these bits of code included, the functionality of `TraceDeoptimzation` is somewhat compromised.
