Evenly space gradient stage.
This seems like an experiment at this point because I don't know how to do
this kind of thing on arm.
Numbers from Skylake...
Before:
./out/Release/nanobench --config srgb \
--match gradient_linear_clamp_3color gradient_linear_clamp_hicolor -q 19:48:13
Timer overhead: 36.7ns
! -> high variance, ? -> moderate variance
micros bench
439.92 ? gradient_linear_clamp_3color srgb
2697.60 gradient_linear_clamp_hicolor srgb
437.28 gradient_linear_clamp_3color_4f srgb
2700.50 gradient_linear_clamp_hicolor_4f srgb
After:
micros bench
382.35 gradient_linear_clamp_3color srgb
593.49 gradient_linear_clamp_hicolor srgb
382.36 gradient_linear_clamp_3color_4f srgb
565.60 gradient_linear_clamp_hicolor_4f srgb
Numbers on my Mac Trashcan are about even; there is no
speedup or slowdown between master and this change.
