e67430cca4
The bulk of the implementation is common between 'release' mode (==AOT-ed model) and 'development' mode (for training), the main difference is that in development mode, we may also log features (for training logs), inject scoring information (currently after the Virtual Register Rewriter) and then produce the log file. This patch also introduces the score injection pass, 'Register Allocation Pass Scoring', which is trivially just logging the score in development mode.
