      [builtins] Refactor the remaining Date builtins. · 1e51af1a
      bmeurer authored 
      This migrates the remaining Date builtins to C++ and removes obsolete
intrinsics and JavaScript wrappers. This reduces the overhead imposed
by the Date builtins, and will allow us to optimize them later in the
TurboFan compiler, while the interpreter doesn't need to worry about
them.

      X87: [runtime] Introduce dedicated JSBoundFunction to represent bound functions. · 37d1dd82
      zhengxing.li authored 
        port 97def807 (r33044)

  original commit message:
  According to the ES2015 specification, bound functions are exotic
  objects, and thus don't need to be implemented as JSFunctions. So
  we introduce a new JSBoundFunction type to represent bound functions
  and make them optimizable. This already improves the performance of
  calling or constructing bound functions by 10-100x depending on the
  use case because we avoid the crazy dance between JavaScript and C++
  that was implemented in v8natives.js previously.

  There's still room for improvement in the performance of actually
  creating bound functions, which is also relevant in practice, but
  we already have a plan how to accomplish that later.

  The mips/mips64 ports were contributed by akos.palfi@imgtec.com.

      X87: Partial revert of rest parameter desugaring. · d9cfa729
      zhengxing.li authored 
        port d3f074b2 (r33024)

  original commit message:
  We'll be able to optimize rest parameters in TurboFan similarly to the arguments array. This CL restores the previous behavior, and a follow-on will enable TurboFan optimization.

  (TBR for rossberg since we discussed the revert beforehand. The only changes are a few lines related to tests and rebasing.)

      X87: [builtins] Sanitize the machinery around Construct calls. · 4620a235
      zhengxing.li authored 
        port 374b6ea2 (r32172)

  original commit message:
  There's no point in collecting feedback for super constructor calls,
  because in all (interesting) cases we can gather (better) feedback from
  other sources (i.e. via inlining or via using a LOAD_IC to get to the
  [[Prototype]] of the target).  So CallConstructStub is now only used
  for new Foo(...args) sites where we want to collect feedback in the
  baseline compiler.  The optimizing compilers, Reflect.construct and
  super constructor calls use the Construct builtin directly, which allows
  us to remove some weird code from the CallConstructStub (and opens the
  possibility for more code sharing with the CallICStub, maybe even going
  for a ConstructICStub).

  Also remove the 100% redundant HCallNew instruction, which is just a
  wrapper for the Construct builtin anyway (indirectly via the
  CallConstructStub).

  Drive-by-fix: Drop unused has_function_cache bit on Code objects.
