Halffloats have a limited range. It shouldnt normally come up, but if the scale value passed in produces a small value, the half floats will be denormals, which are slow and/or flust to zero. This test ensures they behave the same in C and SIMD and tests the performance of denormals.

Removes low levels for I420ToBGRA and I420ToRAW and reimplements them as I420ToRGBA and I420ToRGB24 with transposed color matrix. Adds unittests that do 1 step conversion vs 2 steps to test end swapping versions match direct conversions.

swap U and V and transpose conversion matrix, so I420AlphaToARGB and I420AlphaToABGR share low level code. Having less code with same performance allows more focused optimization for future ARM versions.
