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

Update parser whitespace for clarity (#8539)
* Update parser whitespace for clarity

Has the nice benefit of not requiring a charCode to String conversion.

* Remove test262 exceptions

Per https://github.com/tc39/ecma262/pull/1218#issuecomment-395340891,
ECMA262 follows whatever the latest Unicode version specifies for Zs
Space_Separator category. MONGOLIAN VOWEL SEPARATOR was moved to the Cf
Other_Format category in Unicode 8.

afd0638b74 Reuse hash token instead of new primaryTopicToken
Set whether we're in a pipeline in order to determine how to parse the
hash. The error message changes as a result, since the `hash` never
enters the block.
