PPC/s390: [builtins] Introduce a proper BUILTIN frame type.

Port f47b9e981035c887bda5ae66203e458eb37a5a65

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.
