2a0f5f111c 1F1: more changes to negative a and b domain. 
* Bessel approximation is now good for b-2a <= 0 via Tricomi's relations.
* Selection condition based on convergence is now more rigorous, or at least more conservative.  But...
* Error rates are much higher because a poorly converging bessel approximation has slightly less cancellation than the generic series.  Hopefully this can be fixed via https://dlmf.nist.gov/13.13.  And...
* We need to rewrite these new versions to use recurrence relations on the Bessel functions (but these need to be backwards, so we would calculate and cache say 50 evaluations, then the next 50 and so on).  And...
* Bessel approximations can underflow spuriously when b is large.... really need a log_bessel_j to fix this as we will be multiplying by tgamma(b).

Fix a couple of minor issues in the implementation to improve error rates.
NB: errors very near the singularity are still very high - this is an intrinsic property of the function - we are solving z = w exp(w) for w, but there are actually a wide range of w values which satisfy the equation once we get very close to the singularity.

b4ec109b83 tanh_sinh: change calculation method used for scaling ranges: 
"naive" method is prone to generating a point at the endpoint if the endpoint is large, subtract scaled complement from the endpoint instead.
Open questions:
1) Can this still fail if the endpoint is a very large value?  For example if we have endpoints of [+large, +larger] where the difference between them is small?
2) Do we still need the asserts, or should they be replaced by some other check?
3) If the endpoints are replaced by some other check we could either massage the position to be one representable value below the endpoint, or else simply return 0.  The former risks evaluating at the same point over and over as we go down levels, the latter would seem to be incorrect for functions which do not go to zero at the endpoint.

4fc8d43b4b make move constructor and operator= noexcept 
This change helps the polynomial class play well with STL
containers.

> If the move constructor for an element type in a container
> is not noexcept then the container will use the copy constructor rather
> than the move constructor -- HIC++ Version 4.0

Benchmarking shows that the number of calls to copy constructor
are reduced.
