IMO this makes sense, but I agree with @philnik777 that we should use a new entry point in the dylib for `long double` just like we do for the other types. IMO what this patch is buying us is mostly front-loading of work we'll have to do when we can truly support `long double`, which will now be simplified cause we only need to plug in the missing bits.
