8a00c2d233 GPU: Allow gcc/clang/icc runtime SSE4 usage.
All our builds before were only using SSE4 in jit...

3b1cc0d3b8 softgpu: Limit minX/maxX per line.

9458610d96 softgpu: Avoid rsqrt path for normals.
In LittleBigPlanet, it's noticeable that the lighting is very off due to
the slight loss of accuracy - possibly due to cutoff or similar.

ce8a49b1c1 softgpu: Retain floats in diffuse/specular.
This seems to be a bit more accurate.  Color blending seems correct now,
but the factors and especially pow results are off.

Also, normalize normal to 0, 0, 1, which seems to match results better.

cba2374abd softgpu: Separate calculation of S/T.
We could probably reuse, but we're not right now and it complicates the
logic.

612cc0ab5c softjit: Optimize depth range checks.
This was higher than I expected on the profile.  Not a huge improvement,

5e3bef7e14 samplerjit: Avoid gather if overread could crash.
This should be rare, but a game could easily shove a CLUT4 texture at the
end of VRAM, and then accessing the last index would segfault.

7594187538 softgpu: Skip sample lookup if masked.
Was hoping making other things faster would make this unnecessary or
worse, but it hasn't seemed to.  This gives a pretty decent improvement in
most places (~4%.)

a0fe4d06bf softgpu: Stop specializing on miplevels.
Now that samplerjit is processing mips, it no longer helps.  Just
complexity now.

355bad666c softjit: Optimize common case bloom blending.
Bloom often uses fixed ONE + ONE, which is a lot less work for us.  And
bloom often runs over and over again on pixels, so saving work is good.

496545e55c softgpu: Add code for tracking GPU writes.
Unfortunately, it has a pretty noticeable speed impact, even at the basic
"assume everything's written" level.  Compiled off by default, but at
least it's there.

Doesn't account for tests (i.e. alpha test skipping write) so still not
perfectly accurate.
