sycl/test-e2e/Regression/optimization_level_debug_info_specopt.cpp is failing

### Describe the bug

This is failing on the llvmspriv_pulldown branch.

### To reproduce

1. Include a code snippet that is as short as possible
2. Specify the command which should be used to compile the program
3. Specify the command which should be used to launch the program
4. Indicate what is wrong and what was expected

### Environment

- OS: [e.g Windows/Linux]
- Target device and vendor: [e.g. Intel GPU]
- DPC++ version: [e.g. commit hash or output of `clang++ --version`]
- Dependencies version: [e.g. the output of `sycl-ls --verbose`]

### Additional context

_No response_

Start with sycl/test-e2e/Regression/optimization_level_debug_info_specopt.cpp on the llvmspriv_pulldown branch and run the relevant test to capture its failure. Compare the observed result with the expected test behavior; the work is done when this regression test passes on that branch.
