Can you have this case call `cfg.cgm.errorNYI()` instead. The constrained
intrinsics require rounding mode and exception behavior arguments that in
classic codegen are part of the IRBuilder state. We haven't implemented that
yet in CIR, so this will result in a bad call. Also, the constrained intrinsics
may be replaced before we get this mechanism properly implemented in CIR.
