This change splits `NodeKind::IdentifierName` into separate node kinds depending on whether the identifier is followed by parameters, and similarly splits `NameQualifier` based on whether the qualifier has parameters. This enables us to only push a pattern block when it's actually needed, rather than "defensively" pushing one when it might be needed. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
