      add Intel Code Analyst markers · a7c87e19
      Frank Barchard authored 
      add macros to enable/disable code analyst around blocks of code.

Normally these macros should not be used, but if performance
details are wanted for intel code, enable them around the code
and then run via the iaca tool, available on the intel website.

      NV12 allow NULL for Y · 17d31e6a
      Frank Barchard authored 
      The conversion from NV12 and other Bi or Tri planar formats, differs only in the UV handling.  The helper function supports passing a NULL for the dst_y channel indicating you only want to do the UV conversion.

      Reimplement NV21ToARGB to allow different color matrix. · 914a9856
      Frank Barchard authored 
      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.
