I don't remember anything in particular. I'd recommend just bootstrapping clang/llvm and seeing what happens, assuming clang will emit these intrinsics if you pass an added cflag to it or something.

It's my impression that halide is great at generating code that hits worst-case behaviors in LLVM. I don't know whether they're users of these invariant intrinsics, however.
