f553db2d30 HalfFloatPlane unittest for denormal half floats 
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.

e2611a7349 document cpuid command line behavior 
cpu_info_ is zero for uninitialized state and all bits are off, disabling all cpu optimizations.
the 1 bit indicates cpu_info_ is initialized avoiding calling the detection code again for performance.

MaskCpuFlags initializes the cpu ignoring existing flags, then masks with the supplied flags and stores to cpu_info_.
As a mask, -1 has no effect, enabling all cpu features that were detected, but nothing that wasnt detected.
Setting to 0 will cause the next call to re-initialize the cpu, which is same as enabling all features.
Setting mask to 1 will turn off all cpu features but keep the initialized bit on, so the next detection call wont reinitialize and the cpu features are all disabled.

So normal behavior for command line and programatic masking is:
1 = C
-1 = SIMD

914a9856c7 Reimplement NV21ToARGB to allow different color matrix. 
Low level for NV21ToARGB written to accept yuv matrix used by
other YUV to ARGB functions.
Previously NV21 was implemented for Windows using NV12 with a different
matrix that swapped U and V.  But the Arm version of the low level does
not allow the matrix U and V contributions to be swapped.
Using a new low level function that reads NV21 and uses the same
yuvconstants as other YUV conversion functions allows an Arm port of
this function.

05416e2d9a Box filter for YUV use rows with accumulation buffer for better memory behavior. The old code would do columns accumulated into registers, and then store the result once. This was slow from a memory point of view. The new code does a row of source at a time, updating an accumulation buffer every row. The accumulation buffer is small, and should fit cache. Before each accumulation of N rows, the buffer needs to be reset to zero. If the memset is a bottleneck, it would be faster to do the first row without an add, storing to the accumulation buffer, and then add for the remaining rows.

As clangcl mimics both Visual C and GCC, ifdefs need to pick one or the other or often you'll end up with both. In this CL we disable most Visual C code and use the GCC versions which allow assembly for both 32 and 64 bit intel.

292c2286a6 prototype of a YUV to RGB function to achieve higher quality and performance at the same time. The chroma is made more accurate by using negative values that allow more range and then subtract the contributions from the luma contributes. The luma is made more accurate using a multiply that duplicates the Y bits out to 16 bits and then does a 2.14 bit fixed point coefficient. The replication is done for free as part of the multiply.
