Jens Johansen 76e2c48428 [parser] Support record type in variable pattern 
When seing a '(' after a var/final in `parseVariablePattern` require a
type --- the only allowed thing is a record type, but we can't
generally allow for instance `() async =>` as a record type as that
normally means something else.
