port 75f6ad74 (r31089).

    original commit message:
    Adds support for calling runtime functions from the interpreter. Adds the
    CallRuntime bytecode which takes a Runtime::FunctionId of the function to call
    and the arguments in sequential registers. Adds a InterpreterCEntry builtin
    to enable the interpreter to enter C++ code based on the functionId.

    Also renames Builtin::PushArgsAndCall to Builtin::InterpreterPushArgsAndCall
    and groups all the interpreter builtins together.
