Daniel Andersson a1bc527306 Migrate logging infrastructure Isolate->Thread
This enables thread-safe logging (e.g., ISL_Print, which will soon be renamed to THR_Print), which is needed for concurrent
marking (DetachCode) and compilation.

Make finalization of GC marking tasks concurrent, now that it's thread-safe.
