// needed. Only VM-defined natives are bootstrap natives; they cannot be
// defined by embedders or native extensions.
// - no scope natives, which are called through a wrapper function. The wrapper
// function handles the safepoint transition. The callee is responsible for
// setting up API scopes as needed.
// - auto scope natives, which are called through a wrapper function. The
// wrapper function handles the safepoint transition and sets up an API
// scope.
