Languages like CUDA, HIP etc. have APIs which accept uninitialized function arguments. With D105169 <https://reviews.llvm.org/D105169>, noundef-analysis has been enabled by default and we are forced to assume very strict constraints for the mentioned languages. So, the proposed change is to skip adding noundef attribute to function arguments and return values for such languages.
