* Support internalSlots to babel-types and babel-generator
* Parsing support for internal slot properties
* Print internal slots in babel-generator
* Add whitespace before first internal slot property
* babel-generator: Add TypeScript support
* Remove type declarations; not published from babylon
* Remove TODOs
* Consistently use `this.word` for tokens that are words
* babel-types: Add TypeScript definitions
* Add missing builders
* Allow arrow function to have "generator"
* Replace link to resolved issue with comment

Exposes raw mappings when source map generation is enabled. To avoid the cost of source map generation for consumers of the raw mappings only, `.map` is changed to a getter that generates the source map lazily on first access.
* Support computed class property names (#4499)
** Depends on babel/babylon#121 **
* `babel-types`: Add `computed` field to `ClassProperty`
* `babel-plugin-transform-class-properties`: handle computed property names correctly
* `babel-generator`: add tests for class properties (computed/literal, static/instance)
* doc: Update babel-types with ClassProperty.computed
* chore(package): update babylon to v6.11.0
* babel-types: move ClassProperty.computed to be last builder arg
Previously we saw a bug that when we have nested if statements
and an alternate then the generated code may confuse which
if statement the alternate belongs to.
e.g.
```
if (foo) if (bar) bar(); else baz();
```
But this was handled by looking at the consequent
and if it's an if we add a block. However we didn't
handle situations where it's not an if but the last
recursive statement is an if:
```
if (foo) while (bar) if (baz) baz(); else shoosh()
```
This handles it by recurring until we get the last
statement.
I'm extremely stupid and didn't commit as I go. To anyone reading this
I'm extremely sorry. A lot of these changes are very broad and I plan on
releasing Babel 6.0.0 today live on stage at Ember Camp London so I'm
afraid I couldn't wait. If you're ever in London I'll buy you a beer
(or assorted beverage!) to make up for it, also I'll kiss your feet and
give you a back massage, maybe.
