      [Parser] Add support for Zone allocated ConsumedPreParsingScopeData. · 8da9dbbb
      Ross McIlroy authored
      Adds support for zone allocated (off-heap) ConsumedPreParsingScopeData to
      enable worker-thread access to PreParsingScopeData during parallel IIFE
      compile tasks.
      
      In order to avoid code-duplication, a templated
      BaseConsumedPreParsingScopeData is added which implements the logic for
      decoding the bytestream into scope data. Two implementations of this
      base class are instantiated for each of the underlying serialized scope date:
        - ZoneConsumedPreParsedScopeData for exposing ZonePreParsedScopeData
        - OnHeapConsumedPreParsedScopeData for exposing on-heap PreParsedScopeData
      The interface for each of these classes is the ConsumedPreParsingScopeData,
      which exposes the methods required by the parser to deserialize the required
      data.
      
      As a side-cleanup, moved Ucs2CharLength and Utf8LengthHelper implementations
      to cc file so that we don't get a linker error if one of them are unused by
      the cc file including the header.

      [compiler] Collect eager inner functions for compilation during renumbering. · a3052cfe
      rmcilroy authored
      This CL modifies the ast-numbering phase to collect function literals which
      should be compiled eagerly. This is then used to eagerly compile the inner
      functions before compiling the outer function. This will be used to queue
      compilation jobs on the CompilerDispatcher in a later CL.
      
      This CL moves the compilation of eager inner functions out of the
      GetSharedFunctionInfo function and instead compiles them explicitly. This
      simplifies GetSharedFunctionInfo and also means there is no need to pass a
      LazyCompilationMode to the function, so this concept has been removed.

      New zone-backed list datastructure to replace ZoneList · 610c0d75
      heimbuef authored
      Since ZoneLists are essentially non-standard ZoneVectors and have a bad
      growing behaviour (ZoneList-allocations make up ~50% of website parse
      zone memory) we should stop using them. The zone-containers are merely
      a clean-up, with none of them actually better suited to be used with
      zones. This new datastructure allows most operations of a LinkedList (
      except pop_first and insertAt/removeAt) but uses about the same memory
      as a well-initialized ZoneVector/ZoneList (<3% overhead with reasonably
      large lists). It also never attempts to free memory again (which would
      not work in zones anyway).
      
      The ZoneChunkList is essentially a doubly-linked-list of arrays of
      variable size.
      
      Some test-results where I tried storing 16k pointers in different list
      types (lists themselves also zone-allocated):
      
      List type                       Zone memory used   Time taken
