b0f71e08f4 Simplify projective texcoord calculation 
As mentioned in https://github.com/hrydgard/ppsspp/issues/17613#issuecomment-1613583152 .

436b49c4f2 Streamline x86 SSE workaround 
Seems clearer than using #ifdef's at each site. Also rationale
is clearly spelled out, one 'Go to definition' away from any instance.

ae9d34370e softgpu: Move wsum_recip out of the triangle loop. 
Seems like a small benefit, but not seeing any issues from this.
Noticed by fp64.

ab85c46161 Use _mm_movemask_ps for AnyMask 
Probably very minor speed improvement, but it's rather neat.

construct/destructs showing in profiles...

07c276c32d softgpu: Fix double rectangle drawing at halfpixel. 
There seems to be some odd behavior with the X start pos, but at least the
end pos should not be drawn twice when using 0.5 - 0.5.

d6750993d7 softgpu: Force alpha test when it could skip blend. 
Blending is slow, and often games do effects like smoke, sun, etc. that
has a lot of zero alpha in them.  Many games do this with alpha testing
off, which is cheap compared to blending.

2c90dafe64 softgpu: Force alpha test off in more scenarios. 
Since we're already checking the CLUT, we can tell if it doesn't contain
zero alpha, in which case a != 0 test will never fail.  This is actually
pretty common, even when texture alpha is not always FF.

00e76b11b6 softgpu: Optimize > non-zero alpha tests as well.

4d92533907 softgpu: Apply optimizations to states generically. 
This is for optimizations we can only do when we know the vertex values.

6bd0eec54d softgpu: Calc flags on state as we queue verts. 
Might be some other ways, like doing this directly in a vertex reader.
Also am thinking about doing things regarding UVs or positions.

Flags not yet used, keeping separate for perf checks.

4d06400548 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.

d8716b5d90 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.

softgpu: Better approximate slope mip level mode (#16276) 
* 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.

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.)
