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.

0ebda3c33e hygiene / block scoping improvement (#608)

Closes #605.

block_scoping pass had a bug with closure in for statement with let or const. This pr fixes it by extracting a loop body as a variable.
Closes #604.
