      [runtime] Kill the %NumberToIntegerMapMinusZero runtime entry. · 4b235ade
      bmeurer authored 
      This was initially used to special case some weird date.js behavior, but
has since been abused in other areas. In case of the string character
access, everything that is outside the Smi range cannot be a valid
string index anyways, so %NumberToSmi is perfect here in either case,
and for ToPositiveInteger it's better to just use ToInteger adding +0 to
turn -0 into +0.

      X87: [Interpreter] Support compiling for baseline on return from interpreted function. · 45005083
      zhengxing.li authored 
        port f241a61a (r36360)

  original commit message:
  We cannot tier up from interpreted to baseline code when there is an
  activation of the function on the stack. This significantly regresses
  the performance of recursive functions since they are unlikely to get
  tiered up.

  This CL adds the ability for a function to be marked for baseline
  compilation when it returns. To do this we patch the
  InterpreterEntryTrampoline return address to point to
  InterpreterMarkBaselineOnReturn, which leaves the
  interpreted frame and recompile the function for
  baseline.

  This improves the score of EarlyBoyer by ~8x for Ignition.

      X87: [Interpreter] Fix incorrect frame walking in arguments create stubs. · d748daa3
      zhengxing.li authored 
        port 40f34541 (r36181)

  original commit message:
  The previous approach taken by FastNew[Sloppy,Strict,Rest]ArgumentsStub
  looked at the function slot in order to skip stub frames
  and find the JS frame. However, stub frames do not have a
  function slot (in fact their fixed frame ends one slot
  before the JS frame's function slot). Therefore, if this
  location in the stub frame happens to have the function
  object the create arguments stubs won't skip this frame
  correctly.

  Replace this approach with one where the stub is
  specialized to either skip a frame if required (since
  there will only ever be one extra frame on Ignition
  the loop approach isn't necessary).
