FWIW, this isn't quite correct with ARB_shader_precision or GL4.1 --
it specifies that infinities should be correctly generated through
division by 0, which unsafe-fp-math doesn't guarantee. At least,
that's assuming this is similar to the "fast" per-instruction flag

Include compute shaders as well, which only affects TGSI and thus OpenGL.
