traceur.compile moduleName fix

Allows `moduleName` option as a string for `traceur.compile` into AMD and instantiate
to output correctly named define statement
Extract spread runtime code into a new file

The intent is to make the runtime library more modular.

See #1007
Use undefined as trigger for default value for destructuring

Previously we used an in check which is no longer the semantics
of ES6.

Fixes #1013
Show the whole error stack on load failure

This is in reference to issue #1018

Currently only the original error message is shown. This pull request includes the whole error stack, which immediately points the user to the offending failing line.

Closes #1019.
Fix issue with object literal in the destructuring initializer

When we have

```js
({x = {y: 1}} = expr);
```

we ended up transforming `{y: 1}` as well which leads to an invalid
parse tree.

Fixes #1011
Extract class runtime functions into own file

See #1007
Extract generator runtime into its own file

See #1007
Move Object assign, is and mixin to polyfill directory

Move these method out of runtime.js

See #1007
Calling .next() on a closed generator shouldn't throw

`next()` on a closed generator should just return `{value: undefined, done: true}` instead of throwing an exception.

Fixes #841

Closes #1006, closes #841.
Catch rejections in WebPageTranscoder.

Remove call to ErrorReporter inside of Loader: all callers of Loader
are responsible for error handling via reject handlers.

Fix latent error codeUnit.address_.

Follow-on fix to issue #1018.

Added Set and updated Map to include iterators

This adds:
- Set
- forEach for Map and Set
- entries, values & keys to Map
- values to Set
Calling g.throw(e) on a closed generator g should throw e, not a new error.

According to 6 and 7 of https://people.mozilla.org/~jorendorff/es6-draft.html#sec-generator.prototype.throw, calling the throw method on a closed generator should throw the error passed in, not a new error.

Fixes #1025.

Depends on #1006.
Use an object's `@@iterator` method when spreading

Instead of converting the argument to an object and assuming it is an array-like object with numeric properties and a length property, $traceurRuntime.spread should use the object's @@iterator method and throw a TypeError when the argument is not an object.

See http://people.mozilla.org/~jorendorff/es6-draft.html#sec-runtime-semantics-arrayaccumulation

Fixes #842
