With the Ignition + Turbofan pipeline there is very little overlap between the data needed for unoptimized compilation and optimized compilation. As a result, it is cleaner to split up the CompilationInfo into UnoptimizedCompilationInfo and OptimizedCompilationInfo. Doing so also necessitate splitting up CompilationJob into UnoptimizedCompilationJob and OptimizedCompilationJob - again there is not much overlap so this seems cleaner.
