      PPC/s390: [Interpreter] Adapt Call bytecode handlers to drop their stack-frame. · e5b93bd5

          This change adapts the Call bytecode handlers such that they don't require
          a stack frame. It does this by modifying the call bytecode handler to
          tail-call the Call or InterpreterPushArgsAndCall builtins. As a result, the
          callee function will return to the InterpreterEntryTrampoline when it returns
          (since this is the return address on the interpreter frame), which is
          adapted to dispatch to the next bytecode handler. The return bytecode
          handler is modified to tail-call a new InterpreterExitTramoline instead
          of returning to the InterpreterEntryTrampoline.
      
          Overall this significanlty reduces the amount of stack space required for
          interpreter frames, increasing the maximum depth of recursive calls from
          around 6000 to around 12,500 on x64.
