Ross McIlroy 1e5b6d99f4 [RCS] Create thread local runtime call stats tables for worker threads 
Creating a runtime call stats table for each worker thread task is expensive.
Instead we create a single table per thread, and use TLS to get the correct one
when starting a worker thread task.

In order to correctly initialize the parser, scanner and parse-info's runtime
call stats fields, we move creation of the scanner and parser onto the
background tasks for BackgroundCompileTask and UnoptimizedCompilationJob.
