I did this to start with, but then alignment kept being broken
during refactorings, and at some point I switched to not aligning,
and now we have a big mess.
Add a php-cs-fixer rule to consistently not align phpdoc tags.
Types omitted in two places where we violate them currently:
Namespace_::$stmts can be null during parsing, and Enum_::$scalarType
can be a complex type for invalid programs.
The formatting in this project has become something of a mess,
because it changed over time. Add a CS fixer config and reformat
to the desired style, which is PSR-12, but with sane brace placement.
