Leonardo de Moura 2fc775954c fix: error recovery
@kha We have a few parsers that invoke `tokenFn`, and return error
depending of what is on the top of the stack (e.g., `ident`).
These parsers were not restoring the stack size when reporting errord,
and messing up the error recovery. We never notice the problem because
operators such as <|> restore the stack size, and we were not trying
to elaborate syntacticly incorrect terms.
