      [lite] Allocate feedback vectors lazily · 7629afdb
      Mythri authored
      Allocate feedback vectors lazily when the function's interrupt budget has
      reached a specified threshold. This cl introduces a new field in the
      ClosureFeedbackCellArray to track the interrupt budget for allocating
      feedback vectors. Using the interrupt budget on the bytecode array could
      cause problems when there are closures across native contexts and we may
      delay allocating feedback vectors in one of them causing unexpected
      performance cliffs. In the long term we may want to remove interrupt budget
      from bytecode array and use context specific budget for tiering up decisions
      as well.

      [elements] Rename Has*Elements and Is*ElementsKind methods · 7915cf93
      Mathias Bynens authored
      Commit 26c00f4a improved the names of
      most FAST_* elements kinds in the enum. This patch updates the matching
      Has*Elements and Is*ElementsKind method names accordingly.
      
      - HasFastSmiElements => HasSmiElements
      - IsFastSmiElementsKind => IsSmiElementsKind
      - HasFastObjectElements => HasObjectElements
      - IsFastObjectElementsKind => IsObjectElementsKind
      - HasFastSmiOrObjectElements => HasSmiOrObjectElements
      - IsFastSmiOrObjectElementsKind => IsSmiOrObjectElementsKind
      - HasFastDoubleElements => HasDoubleElements
      - IsFastDoubleElementsKind => IsDoubleElementsKind
      - HasFastHoleyElements => HasHoleyElements
      - IsFastHoleyElementsKind => IsHoleyElementsKind
      
      Additionally, FastHoleyElementsUsage is renamed to HoleyElementsUsage.

      In the shell sample don't print the result of executing a script, only
      evaluating expressions.
      
      Fixed issue when building samples on Windows using a shared V8
      library.  Added visibility option on Linux build which makes the
      generated library 18% smaller.
      
      Changed build system to accept multiple build modes in one build and
      generate seperate objects, libraries and executables for each mode.
      
      Removed deferred negation optimization (a * -b => -(a * b)) since this
      visibly changes operand conversion order.
      
      Improved parsing performance by introducing stack guard in preparsing.
      Without a stack guard preparsing always bails out with stack overflow.
