Currently, clang-offload-bundler has -inputs and -outputs options that accept values with comma as the delimiter. This causes issues with file paths containing commas, which are valid file paths on Linux.
This add two new options -input and -output, which accept one single file, and allow multiple instances. This allows arbitrary file paths. The old -inputs and -outputs options will be kept for backward compatibility, but are not allowed to be used with -input and -output options for simplicity. In the future, -inputs and -outputs options will be phasing out.
