    [parser] Unify and simplify handling of "null" types · d52010e0
    Adam Klein authored
    Before this patch, the parser mixed mixed "Null" and "Empty" as names
    for null placeholder instances in ParserBase. Confusingly, those meant
    different things in case of Statements.
    
    This patch uses "Null" anywhere the meaning is "== nullptr" in the Parser.
    It also makes use of std::nullptr_t and templatized IsNull() methods to
    reduce the amount of boilerplate needed in both the Parser and PreParser.
