[PATCH] D20493: [CUDA] Add -fcuda-approx-transcendentals flag.

[Justin Lebar via cfe-commits]

More tightly scope the __USE_FAST_MATH__ macro.

tra pointed out that device_functions.hpp uses __USE_FAST_MATH__ for its own
purposes.  For this CL, we only want to define __USE_FAST_MATH__ around
math_functions.hpp.
