X87: [runtime] Introduce FastNewStrictArgumentsStub to optimize strict arguments.

  port 09d845354742a90fc0596262eb5cbaac169e5ed9(r33925)

  original commit message:
  The FastNewStrictArgumentsStub is very similar to the recently added
  FastNewRestParameterStub, it's actually almost a copy of it, except that
  it doesn't have the fast case we have for the empty rest parameter. This
  patch improves strict arguments in TurboFan and fullcodegen by up to 10x
  compared to the previous version.

  Also introduce proper JSSloppyArgumentsObject and JSStrictArgumentsObject
  for the in-object properties instead of having them as constants in the
  Heap class.

  Drive-by-fix: Use this stub and the FastNewRestParameterStub in the
  interpreter to avoid the runtime call overhead for strict arguments
  and rest parameter creation.
