I wonder if this should add `"no-builtins"` as well. I don't really know what that does that `"no-builtins"` doesnt, but I noticed that there's some logic in the `TargetLibraryInfo` that optionally takes a function and disables all libcalls if it has `"no-builtins"` so it's possible something we should propagate.
