The `llc-vector-store-scalarize.ll` test case fails when running with `DLLVM_ENABLE_EXPENSIVE_CHECKS` enabled.
It causes us to reach and report a fatal error, (here)[https://github.com/llvm/llvm-project/blob/f78d6caadc60b58a6cf390efc2b3d2da7a21caef/llvm/lib/Passes/StandardInstrumentations.cpp#L1413], and reports the following:
```
LLVM ERROR: Function @store_array_vec_test changed by ScalarizerPass without invalidating analyses
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
