Tests for changes or regressions in the generated micro-ops. This will be
instrumental in my development of the micro-ops optimizer, and my plans to
phase out some of the macro-op optimization passes in favor of doing those
optimizations on the uop level instead.
rgb24 16x16 -> rgb24 16x32:

min: {0 0 0 _}, max: {255 255 255 _}
[ u8 ...X] SWS_OP_FILTER_V : 16 -> 32 bilinear (2 taps)
min: {0 0 0 _}, max: {255 255 255 _}
