Merge pull request #6273 from ooflorent/fix-4857/unreachable_branches 
Eliminate unreachable branches
 2018-01-12 10:55:27 +01:00
Florent Cailhol c9ff97fa7e Eliminate unreachable branches 
Webpack does not transpile unreachable branches leaving `import` expressions
in the code. This PR modifies `ConstPlugin` to remove the unreachable branch.

Before:

```js
if (true) { 1 } else { import("a") }
if (false) { import("a") } else { 1 }
true ? 1 : import("a");
false ? import("a") : 1;
```

After:

```js
if (true) { 1 } else {}
if (false) {} else { 1 }
true ? 1 : null;
false ? null : 1;
```

Cody Ogden f5b57f4764 Extract TrackingSet class from the Parser.js module. 
@TheLarkInn suggested this class be extracted from this file during the live stream tonight. A similar class was removed and placed in the  directory.
