Previously we were treating the local `NullGrammar` differently from `atom.grammars.nullGrammar`. These two grammars are conceptually the same, as the former was created to support editors creation without a grammar registry. To keep backwards-compatibility, we also build placeholder lines on-demand when calling `TokenizedBuffer.prototype.tokenizedLineForRow`. This ensure that packages relying on the internals of `TokenizedBuffer` to retrieve syntactic boundaries won't break when the null grammar is used or large file mode is on.
