X87: [builtins] Introduce a proper BUILTIN frame type.

  port f47b9e981035c887bda5ae66203e458eb37a5a65 (r37051)

  original commit message:
  This adds a new BUILTIN frame type, which supports variable number of
  arguments for builtins implemented in hand-written native code (we will
  extend this mechanism to TurboFan builtins at some point). Convert the
  Math.max and Math.min builtins to construct a BUILTIN frame if required.

  This does not yet work for C++ builtins, but that'll be the next step.
