softgpu: Split clippos out of rasterization vert.
...
We don't use it, except w, at all in rasterization, so no need to keep it
in the bin queue.

Sometimes the vertex color or alpha can allow us to optimize away some
multiplication.

There's no real benefit to this with only two values.
Not much of a gain perf wise, but still good to transfer less data.

softgpu: Correct accuracy of fog calculation.

This matches values from a PSP exactly, with the help of immediate mode
vertex values (since this directly allows specifying the fog factor
without any floating point math.)

softgpu: Check depth test early on simple stencil.
...
If we don't need to write stencil on sfail/zfail, we can do the depthtest
early, which allows us to more often skip texture sampling.
This gives a good improvement in Chains of Olympus.

Some math was overflowing in allocations, and it would allocate zero
