Avoid freezing objects that don't benefit from it

This gives applications more rope to play with in case they have
any reasons for changing some values of the default constants.

Freezing strings for Hash assignments still speeds up MRI, so
we'll keep on doing that for now (and as long as MRI supports
frozen strings, I expect them to always be faster for Hashes
though I'd be very happy to be proven wrong...)
