1d61041985 ShaderGen: Don't use interface blocks on Vulkan without GS 
Doing so causes the Adreno driver to choke and spew errors about
too many output locations/components, when clearly we're under
the limit.

68cb24172b ShaderGen: Omit some unused varyings when possible 
Removes the clipPos varying unless slow-depth is used, and the
clipDistance varyings if geometry shaders are not used.

0c0d66809d PixelShaderGen: Split bbox into seperate variables 
The Metal shader compiler fails to compile the atomic instructions
when operating on individual components of a vector. Spltting it
into four variables shouldn't make any difference for other
platforms, as they are accessed independently.

56fdcf5f00 VideoCommon: remove unnecessary floor() 
floatindex is clamped to the range [0, 9]. For non-negative numbers
floor() is equivalent to trunc(). Truncation happens implicitly when
converting to uint, so the floor() is unnecessary.

3ad7812b53 ShaderGen: Drop broken fragment shader index workaround for Vulkan 
AMD appears to have since fixed this in their driver, and it makes
shadergen ever so slightly less messy.

bae1168fe9 PixelShaderGen: Ensure all components of ocol1 are initialized 
This was causing a warning in the shader compiler, as the rgb components
were not initialized. Which shouldn't be an issue, as the rgb is not
used in the blend equation, only the alpha. However, the lack of
initialization causes crashes in Intel's D3D shader compiler, so we'll
play nice and initialize all the channels.

50a476c371 Assert: Uppercase assertion macros 
Macros should be all upper-cased. This is also kind of a wart that's
been sticking out for quite a while now (we avoid prefixing
underscores).

ceb1f8c8cb Enable shader_framebuffer_fetch blend path on ubershaders 
Tested on a linux Intel Skylake integrated graphics with
blend_func_extended force-disabled, as it's the only platform I have
that doesn't crash with ubershaders and supports fb_fetch

8d68adcaf3 Workaround qualcomm driver bug 
It seems it doesn't like modifying inout variables in place - so instead
use a temporary for ocol0/ocol1 and only write them once at the end of
the shader

29a9ed043b Implement dual-source blending in shader 
For some GLES drivers that don't support dual-source blending, but do
support GL_EXT_shader_framebuffer_fetch, this might be useful.

efb9759862 LightingShaderGen: Always calculate lighting for both color channels 
Cel-damage uses the color from the lighting stage of the vertex pipeline
as texture coordinates, but sets numColorChans to zero.

We now calculate the colors in all cases, but override the color before
writing it from the vertex shader if numColorChans is set to a lower value.

84f8ebd95f VideoBackends: Clear uid bits that are unused for the current backend 
Currently, this is only the logic op bit, but this will be extended to
the framebuffer fetch/blend modes. In the future, when/if we move to
VideoCommon pipelines, this state will be part of the pipeline UID
anyway, and we can mask it out in the backend by using a two-level map,
so the shaders/programs are shared.
