Chip Hogg 6c73947fe0 Satisfy complaint 
This line shouldn't _actually_ ever be reachable, but I can't fault the
compiler for not figuring that out.

Chip Hogg 04b80f0827 Use wheel factorization for prime numbers 
Certain existing units in the library require very large prime
numbers---so large, in fact, that our naive trial division hits the
_iteration limit_ for `constexpr` loops.  We don't want to force users
to provide a compiler option override, so we'd better find another way.

The solution is to use the "wheel factorization" algorithm:
https://en.wikipedia.org/wiki/Wheel_factorization

This lets us skip most composite numbers in our trial division.  The
implementation presented here is configurable in terms of the size of
the "basis" of primes we use.  Bigger bases let us skip more primes, but
at the cost of storing more numbers.  Fortunately, it turns out that N=3
was good enough for our purposes.
