It stores both the konst selection value for alpha and color channels (for two tev stages per ksel), and half of a swap table row (there are 4 total swap tables, which can be used for swizzling the rasterized color and the texture color, and indices selecting which tables to use are stored per tev stage in the alpha combiner). Since these are indexed very differently, the old code was hard to follow.
Adds a pass to process driver deficiencies between UID caching and use, allowing a full view of the whole pipeline, since some bugs/workarounds involve interactions between blend modes and the pixel shader
Spirv-cross's MSL codegen makes the amazing choice of compiling calls to inout functions as `State temp = s; call_function(temp); s = temp`. Not all Metal backends handle this mess well. In particular, it causes register spills on Intel, losing about 5% in performance.
Previously we were using this workaround when using framebuffer fetch
to emulate dual source blending, but it seems like we also need to use
it when using framebuffer fetch to emulate logic ops, otherwise some
Adreno devices get a crash when compiling OpenGL ES ubershaders.
Using the workaround in specialized shaders doesn't seem to be
necessary, but I've made the same change there for consistency.
This gets us closer to fixing https://bugs.dolphin-emu.org/issues/12791
but doesn't actually fix it.
It doesn't make sense for alpha to add the bias ONLY when dividing by 2, while color doesn't apply the bias for divide by 2 only; hardware testing indicates that alpha should have the bias.
This fixes the menus in Mario Kart Wii (https://bugs.dolphin-emu.org/issues/11909) but reintroduces the white rectangle in Fortune Street.
This reverts commit 5aaa5141ed (and several other matching changes elsewhere).

This fixes rendering issues in Viewtiful Joe (https://bugs.dolphin-emu.org/issues/12525), but it is not entirely hardware accurate, as hardware testing showed other, more complex behavior in this case. However, it should be good enough for our purposes.
Previously we set the texture coordinate to zero, now we set
the texture coordinate *index* to zero. This fixes the ripple
effect of the Mario painting in Luigi's Mansion.
This change should have no behavioral differences itself, but allows for changing the behavior of out of bounds tex coord indices more easily in the next commit. Without this change, returning tex0 for out of bounds cases and then applying the fixed-point logic would use the wrong tex dimension info (tex0 with I_TEXDIMS[1] or such), which is inaccurate.
