[Clang] [SPIRV] `clang/include/clang/Driver/InputInfo.h:84: const char* clang::driver::InputInfo::getFilename() const: Assertion `isFilename() && "Invalid accessor."' failed.` failure when building openmp for `spirv64-intel` with `-Wl,-O1`

I'm trying to build the OpenMP offloading runtime for `spirv64-intel` target. I've noticed that when linker flags contain `-Wl,-O1`, clang driver crashes on an assertion:
```
clang++: /var/tmp/portage/llvm-core/clang-23.0.0.9999/work/clang/include/clang/Driver/InputInfo.h:84: const char* clang::driver::InputInfo::getFilename() const: Assertion `isFilename() && "Invalid accessor."' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
