Improve bignum comparison (Bug#32463#50)
* src/data.c (isnan): Remove, as we can assume C99.
(bignumcompare): Remove, folding its functionality
into arithcompare.
(arithcompare): Compare bignums directly here.
Fix bugs when comparing NaNs to bignums.
When comparing a bignum to a fixnum, just look at the
bignum’s sign, as that’s all that is needed.
Decrease scope of locals when this is easy.
* test/src/data-tests.el (data-tests-bignum): Test bignum vs NaN.
