`CodeCompletioString::getName()` was used only as the sorting keys in
`CodeCompletionContext::sortCompletionResults()` which is effectively
deprecated. There's no reason to check them in `swift-ide-test`. Instead,
check `printCodeCompletionResultFilterName()` that is actually used for
filtering.
Annotate cross-actor references to global actors as `async` and mark them as not-recommended if they must be executed on a different actor than the current context is on.
