Frank Barchard a7c87e19f0 add Intel Code Analyst markers 
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.

README.md

libyuv is an open source project that includes YUV scaling and conversion functionality.

  • Scale YUV to prepare content for compression, with point, bilinear or box filter.
  • Convert to YUV from webcam formats.
  • Convert from YUV to formats for rendering/effects.
  • Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
  • Optimized for SSE2/SSSE3/AVX2 on x86/x64.
  • Optimized for Neon on Arm.
  • Optimized for DSP R2 on Mips.
