Add the remaining missing templatizations to allow an initial wiring in of the off-thread factory into streaming compilation finalization. The off-thread finalization is behind a flag, disabled by default: --finalize-streaming-on-background When the flag is enabled, background tasks will perform perform the finalization during their background execution, and will release the parser and compilation jobs once they are no longer needed. The implementation is complete enough for performance testing, but not enough for launch. Notably, there is no support for: * Class boilerplates (the code is marked unreachable), * Exceptions during finalization, i.e. parse/compile warnings/errors, * Allocation sampling, * Logging, * Asm.js, * Parallel complication tasks * Forced source positions (for "NeedsDetailedOptimizedCodeLineInfo()") This patch also adds some tracing events for the various stages of the off-thread finalization (including the main-thread merge) for further performance improvements.
