30d507c915 Add TS support to @babel/parser's Scope (#9766)
* [parser] Allow plugins to extend ScopeHandler

* Directly extend Scope

* Don't use new.target to get the ScopeHandler

* [parser] Add TS enum  support to the Scope

* Remove duplicated options in tests

* Fix

* Fix flow

* Rename tests

* Add tests

* Full typescript support in scope

* Remove BIND_SIMPLE_CATCH

SCOPE_SIMPLE_CATCH was used instead

* Export TS types

* Register function declarations

* Fix body-less functions and namespaces

1) Move this.scope.exit() for functions from parseFunctionBody to the callers.
    Otherwise the scope of body-less functions was never closed.
    Also, it is easier to track scope.exit() if it is near to scope.enter()
2) Register namespace ids for export

* Disallow redeclaration of enum with const enum

4ca35ef8b9 Fix running flow on travis and update flow (#9128)
* Fix running flow on travis and update flow

- ensure bootstrap is run before running flow as we need some generated files for correctly doing typechecks
- ensure that we only ignore the build directory inside the babel folder as currently we ignore everything because travis checks out into ‘/home/travis/build/’

* Fix all flow errors
