Fix implementations of BinaryInteger.sqrt and UnsignedInteger.cbrt to…

… prevent overflow

Expand testing (#4)

This PR adds tests for BinaryInteger.pow and for default implementations in Math and Real. In addition:

The default implementation of cubeRoot is corrected and removed from Math to Real.
A correction is made for an error in the default implementation of Math.phi.
Special values are now handled in the default implementation of Real.hypot.
This PR also includes an incidental simplification of some operator implementations in Complex, which will simplify later testing.

* Add tests for Math and Real, fix default implementations

* Reorder tests for Linux [NFC]

* Remove repetition in Complex operator implementations [NFC]

* Add tests for integer exponentiation

Implement and use an internal function for combining hashes
