Based on #12507 and some tests, seems like negative exponents are also
fixed to a 1.0f result.

This is correct per hardware tests, see #8403 . Note that the PS3 emulator
running PSP HD remasters does not correctly handle this, and applies
specular for negative diffuse factor.

This will help in the future when we defer GL rendering like we did Vulkan - we will be able to use uniforms, but we won't be able to react to the result of these queries immediately.
Also slightly faster though noone will notice.
