      [offthread] Change OffThreadIsolate to LocalIsolate · f1589bbe
      Leszek Swirski authored
      This patch introduces a new LocalIsolate and LocalFactory, which use
      LocalHeap and replace OffThreadIsolate and OffThreadFactory. This allows
      us to remove those classes, as well as the related OffThreadSpace,
      OffThreadLargeObjectSpace, OffThreadHeap, and OffThreadTransferHandle.
      OffThreadLogger becomes LocalLogger.
      
      LocalHeap behaves more like Heap than OffThreadHeap did, so this allows
      us to additionally remove the concept of "Finish" and "Publish" that the
      OffThreadIsolate had, and allows us to internalize strings directly with
      the newly-concurrent string table (where the implementation can now move
      to FactoryBase).
      
      This patch also removes the off-thread support from the deserializer
      entirely, as well as removing the LocalIsolateWrapper which allowed
      run-time distinction between Isolate and OffThreadIsolate. LocalHeap
      doesn't support the reservation model used by the deserializer, and we
      will likely move the deserializer to use LocalIsolate unconditionally
      once we figure out the details of how to do this.

      [offthread] Unify compiler.cc finalization logic · 58b12f63
      Leszek Swirski authored
      This patch unfies the finalization logic between the various unoptimized
      compilation paths in compiler.cc, taking the various post-processings and
      fixups needed for off-thread finalization and performing them in the same
      order for the other finalizations.
      
      It also unifies the general compilation path between streaming script
      compilation, main-thread script compilation, and main-thread lazy
      compilation, making the main-thread paths both use an iterative execution
      and finalization, and making all three use the same job helper methods
      and overall finalization helper.

      [offthread] Allow off-thread bytecode finalization · 455cb6c0
      Leszek Swirski authored
      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.

      [strong] Check strong mode free variables against the global object. · cb7279da
      marja authored
      Gather references to unbound variables where the reference (VariableProxy) is
      inside strong mode. Check them against the global object when a script is bound
      to a context (during compilation).
      
      This CL only checks unbound variables which are not inside lazy functions - TBD
      how do we solve that; alternatives: add developer mode which disables laziness /
      do the check whenever lazy functions are really compiled.
