llvm6: Tweak fast math intrinsics
Looks like they did some refactoring of flags in the backend and this should catch us up! The "unsafe algebra" boolean has been split into a number of boolean flags for various operations, and this updates to use the `setFast` function which should hopefully have the same behavior as before. This was updated in llvm-mirror/llvm@00e900afd
