There aren't remaining uses on `Context` other than `DiagnosticEmitter` itself. I'm adding `SemIRLoc` because I feel odd about having both `Carbon::Check::DiagnosticBuilder` and `Carbon::DiagnosticEmitter<T>::DiagnosticBuilder`, but it seems relatively little additional typing outside the handful of `DiagnosticEmitter` uses on `Context` itself: ``` Context::DiagnosticEmitter DiagnosticEmitter<SemIRLoc> Context::DiagnosticBuilder SemIRLocDiagnosticBuilder Context::BuildDiagnosticFn BuildSemIRLocDiagnosticFn ``` Also clean up #include's while I'm finishing here.
