In Babel 6, we had `@babel/runtime` which _always_ uses `core-js` in its helpers, meaning that anyone who wants to use our helpers in a centralized modular way had to also use core-js, which isn't always ideal.
Early in the Babel 7 alpha, we added a `useBuiltins: true` option that would use separate copies of the helpers that would skip loading `core-js`, but this _still_ requires users to have an indirect npm dependency on `core-js`.
This PR splits our setup into two separate runtimes:
* ```
'plugins': [
['transform-runtime'],
]
```
with `npm install --save @babel/runtime` that just includes our helpers, and relies on users to globally polyfill any APIs they need.
* ```
'plugins': [
['transform-runtime', { corejs: 2 }],
]
```
with `npm install --save @babel/runtime-corejs2` that includes everything `@babel/runtime` does, but also includes a passthrough API for `corejs@2.x` and rewrites all of the helper modules to reference `core-js`.
* Fix private property parsing in Flow
* Flow tests updated
* Fix type error
* Appropriate name was given to test folder
* Fix
* Empty
* Correct type annotation
* Add required changes in generator package
* Add required changes in flow-strip-types

* Add sourcemap examples for identifiers in code generator.
* Generate sourcemaps with exact mappings for identifiers, even if leading/trailing tokens also use that location.
* Save full descriptor instead of only value for private fields.
Decorators can make private fields non-writable, so we need to store this
information somewhere.
The descriptor can also be used to implement private accessors.

@JamesHenry This changes the AST format. CC @DanielRosenwasser for review.
Supports parsing type arguments on tagged template calls.
Should wait on Microsoft/TypeScript#23430 to be merged so we're sure we have the final syntax.
Previously, if the optional `opts` parameter wasn't passed, the _intent_ was to move the function it held into the `callback` parameter and null out the `opts` param - but instead, it was nulling both.
Just default to pipeline "minimal" and true for decorators for ease of use. We are going to remove the stage presets next so it's fine since it will error when using the plugin individually later.

Since these were getting left in, things that loaded the config, and then passed in back to Babel would get `test` and such _twice_, which could lead to either bad configuration merging, or no configuration at all if the patterns were relative to different directories, as was the case in https://github.com/babel/babel-loader/issues/642.
