Subject: [PATCH] Throw more detailed error when compilation fails

Currently the error only shows as something like this

`Uncaught SyntaxError: Unexpected token '??'`

which makes it difficult to track down which file is failing.

New error :

`Uncaught Error: Error compiling file:///.../vs/workbench/browser/parts/editor/editorGroupView.js. SyntaxError: Unex
pected token '??'`
