We made changes so that the raw value is always printed before we try to decode the value: [JDK-8284273](https://bugs.openjdk.org/browse/JDK-8284273) and the we've made it so that we continue with the rest of the register decoding if one of them fails: [JDK-8296469](https://bugs.openjdk.org/browse/JDK-8296469).

@stefank  thanks for that. I had not noticed that we now print the Registers before we print the (previously truncating) register mapping. IT does indeed seem like there is no point in my proposed enhancement now. I will close this PR. I will also close the bug as "not reproducible".
