Few coverage nitpicks for the cmath module (#102067)
- partial tests for cosh/sinh overflows (L535 and L771). I doubt
both ||-ed conditions could be tested.
- removed inaccessible case in sqrt (L832): ax=ay=0 is handled
above (L823) because fabs() is exact. Also added test (checked
with mpmath and gmpy2) for second condition on that line.
- some trivial tests for isclose (cover all conditions on L1217-1218)
- add comment for uncovered L1018
