JDK-8251093 - Improve C1 register allocator logging and debugging support
Description
JDK-8251093 introduced some improved logging which cannot be read by the C1 Visualizer. As the C1 Visualizer is not part of the JDK, we should include the old format again for the output produced by -XX:+PrintCFGToFile to be compatible with the visualizer again. The console output can still use the improved logging of JDK-8251093.
