gallivm: Use new LLVM fast-math-flags API
LLVM 6 changed the API on the fast-math-flags: https://reviews.llvm.org/rL317488 NOTE: This also enables the new flag 'ApproxFunc' to allow for approximations for library functions (sin, cos, ...). I'm not completly convinced, that this is something mesa should do.
