I think this shows a bug with the patch because this seems to be replacing
`[[using gnu: deprected]]` with `[[gnu::deprecated]]`. While this is 1:1 in
this example, consider something like: `[[using gnu: deprected, noreturn]]`
where there are multiple attributes all sharing the same prefix.
I think `using` should be handled in a separate patch; for this PR, I'd
recommend not attempting to fix this situation. But we may not have that
information in Sema, so that may be more involved.
