maya 43e54dd9fc csqrt has a branch cut on the negative real axis, and this requires
delicacy in order to maintain continuity around it.

we have an initial case to deal with a fairly common case: getting
a real number. Avoid dealing with the branch cut in this case by
checking if the real part is negative.

later, -0.0 < 0 is not met, so instead, test for a negative number
using signbit, so negative zero is also treated as a negative number.
