Actually, there are two other calls to loadDialects in this file (in `CodeGenAction::beginSourceFileAction` and `CodeGenAction::lowerHLFIRToFIR`), don't you need to call `addFIRExtensions` there too?

Maybe you could instead add an option to `loadDialects` and call `addFIRExtensions` inside `loadDialects` and propagate the option.
