X87: Partial revert of rest parameter desugaring.

  port d3f074b23195a2426d14298dca30c4cf9183f203 (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.)
