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. |

To get to 100% compatibility, we will need a software renderer as there are games out there that do tricks that can't really be faked in a sensible way. Useful for homebrew too that mix sw and accel rendering.
