[boost] [constrained-value] zero-overhead

One more wish/requirement for cv.

Maybe this is already met?  I haven't checked.

I want to be able to select a policy that does nothing, and on (reasonably
modern compilers) achieve performance comparable to the underlying (int)
type.  That is, I want to use this like logging - where I can switch it off
at compile time and make the overhead negligible.
