Subject: Refactor float to integer conversion to share the same code. 80bit
 Intel/PPC long double is excluded due to lacking support for the abstraction.
 Consistently provide saturation logic. Extend to long double on 128bit IEEE
 extended platforms.

Initial patch with test cases from GuanHong Liu.
Reviewed by Steve Canon.
