Subject: [PATCH] [MLIR][NFC] Ignore clang-tidy `modernize-use-using` check in
 C code (#180326)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In the MLIR C API headers, clang-tidy’s `modernize-use-using` check
reports a large number of type definitions that use `typedef`. In my
IDE, this even causes the `typedef` code to be shown as struck through.
However, in this case it is clearly not possible to replace them with
`using`. This PR suppresses the `modernize-use-using` check for the code
inside `extern "C"` blocks.
