* Update tanh_sinh handling of boundaries.
So that we don't accidentality end up at an end point, even when arithmetic is inexact, and the FP type has no denomrms.

where max_left_index/max_right_index may go to zero if the function being integrated overflows the FP type being used across nearly all of it's range. Fixes https://github.com/boostorg/math/issues/898
xref scipy/scipy#14901
Splits single if statement into two to avoid apparent clang short-circuit bug on M1 Mac platforms.

* 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.
Fixes https://github.com/boostorg/math/issues/833.
