[dxvk] Re-implement early discard with quad granularity 
May perform better on some hardware in situations where we cannot
discard a full subgroup. Closes #753.

261d31cac6 [dxbc] Fix xfb passthrough for system values 
vReg should be always allocated for system values which is
necessary for emitXfbOutputSetup and is already done for
hull shader passthrough.

06c144f075 [dxbc] Store sample positions as vec2 array 
We can append the zeroes in shader code instead. May
improve generated code on drivers that use scratch
memory or temporary uniform buffers for large arrays.

[dxbc] Do not emit GS system values if rasterization is disabled 
Fixes issue in Star Citizen, which declares a max output vertex count
of 128 in a geometry shader which emits eight components per vertex,
which becomes 12 components in DXVK due to the gl_Position builtin.
This should keep us below the magic limit of 1024 output components.

[dxbc] Add option to enable strict sm4-compliat division 
SM4 is defined to return the first source operand if the divisor is zero.
Windows drivers don't do this by default, so we shouldn't do it either.

[dxbc] Reduce length of tessellation i/o arrays to minimum 
This allows us to fix a violation of the Vulkan specification
where using the same location range for per-vertex and per-patch
i/o is illegal.

May also help certain drivers figure out what's actually needed.

[dxbc] Don't enable sample shading for interpolation functions 
Actually doesn't resolve #456, and doesn't make any sense either because
interpolation at a given sample index is apparently supposed to work even
without using sample shading.
