The problem for steady_clock::now() isn't one of precision, it's that
it isn't steady if we don't use the monotonic clock.  We could define
a non-steady steady_clock (with the same precision as system_clock)
but is that helpful to users?  If that's what we want then yes, we can
do the symbol versioning you suggest.
