2dbd7698cc Adjust recursion when using the Bessel function approximation with large z. 
Avoids hitting tgamma on a negative integer, also improves accuracy when b-a-0.5 is close to a negative integer.
Fixes https://github.com/boostorg/math/issues/1034.

9346271a45 Fix Issue 833 (#835) 
* Correct 1F1[-n, -n, x]
To match what Mathematica does.
Fixes: https://github.com/boostorg/math/issues/829

* Pass policy in forwarding call to gamma_q.

* Fix bug in 1F1 recurrence relations when one term goes to zero.
Fixes issue with 1F1[-n, n, n].
Also reduce cancellation error in a = -1 special case.
