- changes tests to check that the real and imaginary part of the go complex
  division result is equal to the result gcc produces for c99
- changes complex division code to satisfy new complex division test
- adds float functions isNan, isFinite, isInf, abs and copysign
  in the runtime package

Fixes #14644.
