Function call support. If this kernel invocation is within a function execution, call_frame() returns the call frame for the function call.

  // If this kernel invocation is within a function execution,
  // call_frame() returns the call frame for the function call.
  CallFrameInterface* call_frame() const { return params_->call_frame; }

  // If not nullptr, the kernel invoke functions defined in the
  // library. E.g., CHECK_NOTNULL(function_library())->Run("Foo", ...).
