For adding stack checks in optimized code, we compute a conservative estimate of the frame size in the case of a deoptimization. Earlier we included the size of arguments adaptor frames used when actual arguments didn't match formal parameter count. Though we don't have an explicit adaptor frame, we should still include the size of these additional arguments when computing the frame size.
