6887ccf6 - [Driver][HIP/SPIRV] Fix crash when llvm-link is executed. (#196074)

[Driver][HIP/SPIRV] Fix crash when llvm-link is executed. (#196074) There is a design limitation (see [InputInfo](https://github.com/llvm/llvm-project/blob/f08b4fff52cdd3fc8fdd962080da089497c00fcc/clang/include/clang/Driver/InputInfo.h#L23)) that is forwarding flags to `llvm-link` when it shouldn't happen. This commit fixes this issue by sanitizing the arguments forwarded to `llvm-link`. This may happen when `clang-linker-wrapper` eventually calls `clang`, which adds the `-Xlinker` flags. Crash reproducer is here: https://gcc.godbolt.org/z/rxvWcvan3. The fix is based on @MrSidims' old PR (#183492). The error started manifesting by default after the switch to the new driver, and the issue has been in the new driver since commit https://github.com/llvm/llvm-project/commit/4c6f398b866030c17fd94dcdca04f4df03c5214c. However, the problem could potentially be triggered by any call to `clang`, regardless of the `clang-linker-wrapper`. --------- Co-authored-by: Dmitry Sidorov <18708689+MrSidims@users.noreply.github.com>
