Sprites interpolate UVs with the same fixed point planes as triangles, and
texture coordinates become texels at 1/16 texel, truncated toward zero, also
in the sampler JIT. Bit exact on gpu/probe exp57 (through mode and transform
mode sprites, nearest and bilinear).

The GE lerps the top and bottom texel pairs, truncates each to 8 bits, then lerps
those vertically. Bit exact on gpu/probe exp52 (also in ppsspp-re tools/geprobe).

Skipping them is only a speed-up, but it changes how states get batched and
optimized, which changes the rendered output (NBA 2K13 and Virtua Tennis
frame dumps). Keep the old behaviour until that's understood.

A code space clear frees the functions the current state points to, but
the state was kept as long as the GE registers didn't change. Track the
clear generations and recompute, also when a compile during the state
computation clears the caches.
Also skip the binner flush for compiles on builds without the software
JIT, where Compile() does nothing.

* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
* Mac/ARM64 buildfix
* Do the same with the hle result log macros
* Rename the log names to mixed case while at it.
* iOS buildfix
* Qt buildfix attempt, ARM32 buildfix
Seeing as SampleLinearLevel is near the top in the profiler,
optimize actual bilinear filtering using SSE2. Solid win in the
synthetic benchmark (https://godbolt.org/z/fqh3xvbGx, also doubles
as correctness check), no visible difference in actual PPSSPP.
Note: profiler suggests that hot part of SampleLinearLevel is
elsewhere.
If the generation count happens to match, would still get a stale pointer
and crash. Let's just make the generation count static so it always
increases.
This is common (for example, maybe a pixel state is updated but sampler is
not), and reduces time spent in ComputeRasterizerState() quite a bit in
Darkstalkers, where jits are available (i.e. Intel currently.)
* 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.
A texture larger than 512 is "valid", but simply wraps/clamps at 512.
Importantly, the texture coords are still calculated at the specified
size, which can be up to 32768.
