**Summary of the problem**
Compiling any program with the `-x cuda` or `-x hip` flags leaves empty directories per compile in `/tmp` that are not cleaned up.

**Details and steps to reproduce**
This happens with both nvidia and amd, for any file (CUDA/HIP/C++ )
Ex: A simple file with nothing CUDA or HIP specific:
```c++
// sample.cc
#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}
```

For CUDA compile with:

```console
clang++ -x cuda sample.cc
```

Or for HIP we compile with

```console
clang++ -x hip sample.cc
```

We can see the temp files being created anew (looking for the newest files):

```console
$ find /tmp -maxdepth 1 -type d -name "*sample*" -printf '%T+ %p\n' | sort -r | head -n 20
2024-07-22+13:25:32.9609698390 /tmp/sample-646dae
2024-07-22+13:25:32.9609698390 /tmp/sample-56e594
2024-07-22+13:25:11.3652665900 /tmp/sample-ad5032
2024-07-22+13:25:11.3652665900 /tmp/sample-1e8723
2024-07-22+13:24:44.7776319390 /tmp/sample-f98e7b
2024-07-22+13:24:44.7776319390 /tmp/sample-f459d6
```

I was able to reproduce this with LLVM 14 and 15. 
I am on CUDA version 11.8 and ROCM 4
