Changing to core-js for polyfills cause annotation inheritance to break in angular2

[user414]

I'm sure it's a side effect of something else, but restoring es6-shim instead of core-js polyfills fix it for me. Here is the angular2 issue with plunker

Another observation is that the mangling that was turned on with the except also break the annotation inheritance so add to remove that from the prod configuration as well

We kept using es6-shim instead of core-js. However, saw recently that this was finally implemented in the latest trunk/beta

angular/angular#11606

via this commit

angular/angular@f5c8e09

and have not tried it since. There's a high likelihood that the workaround and/or using es6-shim instead of core-js is no longer needed but have not tried it yet.
