Unexpectedly failed tests on M1 Mac

Nobody has claimed this yet.

I'm trying to build on my M1 Mac and some tests are failing unexpectedly.

```
❯ clang --version
Apple clang version 13.0.0 (clang-1300.0.29.30)
Target: arm64-apple-darwin21.2.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
```

This is how I built.
```
cmake -G Ninja ../llvm-project/llvm \
-DDEFAULT_SYSROOT="$(xcrun --show-sdk-path)"\ # Needed for Mac Includes
-DLLVM_ENABLE_PROJECTS="clang;mlir" \
-DLLVM_EXTERNAL_PROJECTS="polygeist" \
-DLLVM_EXTERNAL_POLYGEIST_SOURCE_DIR=.. \
-DLLVM_TARGETS_TO_BUILD="host" \
-DLLVM_ENABLE_ASSERTIONS=ON \
-DCMAKE_BUILD_TYPE=DEBUG
ninja -j6
ninja check-mlir-clang
```

The failures look similar to this one.
```

ninja: build stopped: subcommand failed.
```

Am I missing some information here? Have I done something wrong in the build process?

Any advice would be greatly appreciated.

Reproduce with the M1 build commands and run ninja check-mlir-clang, starting with tools/mlir-clang/Test/polybench/linear-algebra/blas/gemm/gemm.c. Inspect clang-mlir.cc around getMLIRType at line 6005 and compare the failing test output with the expected FileCheck results. Done means the relevant check-mlir-clang tests complete without the assertion.
