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. Differential Revision: http://reviews.llvm.org/D2804 Pull in r232107 from upstream compiler-rt trunk (by Ed Maste): Use signed int implementation for __fixint Requested by: emaste
