Fix version of regenerator-runtime (#644)
7.7.7 is version of @babel/runtime, not regenerator-runtime. Looks like
the intended version was "0.11.0" as you can see in the yarn.lock:

    regenerator-runtime@^0.11.0:
      version "0.11.1"
      resolved "https://registry.yarnpkg.com/regenerator-runtime/-/re...
      integrity sha512-MguG95oij0fC3QV3URf4V2SDYGJhJnJGqvIIgdECeODCT9...

480015d407 block_scoping: handle variable infection (#610)
Handle variable infection in the block scoping pass. 

i.e. In the code below, v is 'infected' by i.
```js
var functions = [];
for (let i = 0; i < 10; i++) {
   let v = i;
   functions.push(function() {
       return v;
   });
}
functions[0]() // should print 0
```

Closes #609.
