Bug

**What is the current behavior?**

Consider the following code:

```js
const forwardRefComponentLike = function forwardRefComponentLike(_props, _ref) {
  return <span>FowardRef</span>;
};

const FowardRefComponent = React.forwardRef(forwardRefComponentLike, {});

const MemoOfFowardRefComponent = React.memo(FowardRefComponent);
```

The `MemoOfFowardRefComponent` component does not pick up the name of the ForwardRefComponent and is instead rendered in devtools as:

```
 Anonymous [Memo]
    forwardRefComponentLike [ForwardRef]
```

See this codesandbox for a demo and a comparison of how React.memo handles regular functional components: https://codesandbox.io/s/react-forwardref-and-memo-combo-33vx7

**What is the expected behavior?**

I would expect this to pick up the name of the thing passed into React.Memo, as happens for regular components

```
forwardRefComponentLike [Memo]
```

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

Tested with React 16.9.0.

   This is a slightly annoying indirection.
   It is currently necessary because DevTools wants to use unique objects as keys for instances.
   However fibers have two versions.
   We use this set to remember first encountered fiber for each conceptual instance.
  function getPrimaryFiber(fiber: Fiber): Fiber {
    if (primaryFibers.has(fiber)) {
      return fiber;
    }
    const {alternate} = fiber;
    if (alternate != null && primaryFibers.has(alternate)) {
