softgpu: Fix compile hazard while running.
...
This prevents any clearing of cache while other threads may be using
previously cached funcs, and avoids wx exclusive hazards.

softgpu: Fix off-by-one rendering after half-pixel.
...
If the X is after a half-pixel offset, the first pixel we draw is the next
one. This wasn't being accounted for properly in one place.

* samplerjit: Remove unused x/y parameters.
Still need to tune the accuracy of filtering, but those were not the
right way.
* softgpu: Better approximate slope mip level mode.
This isn't exactly right, but it's closer.
* softgpu: Calculate auto from largest difference.
Direction shouldn't matter.

Can't round to the pixel when calculating the S/T deltas.
This fixes issues in Wipeout (#16131 ) and Call of Duty bloom.

softgpu: Correct drawing outside TL of rectangle.
...
If the start coordinate was something like 51.75, we were incorrectly
drawing to 51. This can be seen in the Metal Slug intro (#15755.)

We don't use it, except w, at all in rasterization, so no need to keep it
in the bin queue.

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.

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.
