#184545 default-enables the IO sandbox in assert-builds. This causes Clang using Polly to crash (#188568). The issue is that `PassBuilder` uses `vfs::getRealFileSystem()` by default which is considered a IO sandbox violation in the Clang process. With this PR store the VFS from the `PassBuilder` from the original `registerPollyPasses` call for creating other `PassBuilder` instances. This PR also adds infrastructure for running Polly in `clang` (in addition in `opt`). `opt` does not enable the sandbox such that we need separate tests using Clang. Closes: #188568
