[llvm-branch-commits] [clang] [CIR] Replace nsw/nuw unit attrs with OverflowFlags BitEnum (PR #195618)

I like the idea of aligning this with the LLVM overflow flag representation, but it's not clear to me why you aren't using the same assembly format as the LLVM dialect.

I've made a comment on the Saturated flag, but it really feels like we went the wrong direction in our handling of that.
