pl/math: Fix subnormal handling in atan2
Previously subnormals were handled specially when determining from the
exponent whether to shortcut calculating x^8. This was not the correct
approach - to compare with the threshold in such a way that matches
the reference they should be treated the name as normal exponents.
Larger errors than previously thought were found in the subnormal
region - a new test has been added in runulp and the threshold has
been updated.
