ba1ec1d5d6 SPU analyser: remove use_ra from HBR 
Since this is a hint instruction, we don't really use reg value here.

243df38360 rsx: Fix VP writes to CC with a MOV instruction

regs disabled. Looks to be the catch-all ELSE in the selection logic.

f12bd8068c rsx: Fragment decompiler fixups 
- Properly test for NaN and Inf when clamping down to fp16
- Optimize divsq a bit; mix(vec, vec, bvec) emits OpSelect which is what
we want here, instead of component-wise selection which is much slower.

abe7188acf rsx: Proper workaround for broken DIVSQ instruction on realhw 
- While mul(0, nan) = nan and 0 / 0 = nan, 0 / sqrt(0) = 0 because of hw
gremlins. normalize(0) is also nan so this behaviour does not work
around that particular case either which makes it even more baffling.

60f3059d22 rsx: Compensate for nvidia's low precision attribute interpolation 
- The hw generates inaccurate values when doing perspective-correct
  interpolation of vertex output attributes and makes the comparison (a ==
  b) fail even when they are a fixed constant value.
- Increase equality tolerance when doing comparisons in fragment
  shaders for NV cards only to work around this issue.
- Teepo fix

463b1b220d rsx: Improve accuracy of shadow compare Ops when non-integer depth formats are used 
- The fixed-point D24S8 format does special Z clamping during compare which matches PS3 behaviour
- D32S8 is a floating point format and comparison with Dref > 1 always fails causing black edges/borders

a668560c68 rsx: Use native half float types if available 
- Emulating f16 with f32 is not ideal and requires a lot of value clamping
- Using native data type can significantly improve performance and accuracy
- With openGL, check for the compatible extensions NV_gpu_shader5 and
AMD_gpu_shader_half_float
- With Vulkan, enable this functionality in the deviceFeatures if
applicable. (VK_KHR_shader_float16_int8 extension)
- Temporarily disable hw fp16 for vulkan
