evaluate pass incorrectly sets values to undefined

I'm not sure if this project is still maintained, but I'm reporting in case.

Not completely sure this is a different issue than #897, but the testcase is different.

```js
'use strict';
function f(x) {
const s = 'AB'[x];
console.log(s);
return Math.floor(1);
}
```
With `evaluate` and no other passes:
```js
"use strict";function f(x){var s="AB"[x];console.log(undefined);return Math.floor(1)}
```
With `babel.transform(inCode, {presets: ['minify', '@babel/preset-env']})`: (maybe #904)
```
