      Add I420ToAR30 10 bit RGB · bb3180ae
      Frank Barchard authored 
      For more complete support of AR30 format, add I420ToAR30 allowing
the new RGB 10 bit format to be used from standard 8 bit I420 format.

Bug: libyuv:751
Test: I420ToAR30 unittest added

      ARGBToAR30 SSSE3 use pmulhuw to replicate fields · c3677514
      Frank Barchard authored 
      AR30 is optimized with 3 techniques
1. pmulhuw is used to replicate 8 bits to 10 bits.
2. Two channels are processed at a time.  R and B, and A and G.
3. pshufb is used to shift and mask 2 channels of R and B

      Using all_dependent_configs to pass libyuv_config around. · d94a4867
      Mirko Bonadei authored 
      Using public_configs, client projects must rely on public_deps to
propagate configurations up in the build graph. This is bad because
public_deps allows the exposition of headers that live in another
target. This can lead to a really unhealthy build.

On the other side, all_dependent_configs is automatically propagated
up in the build graph but if a target includes a libyuv header it is
forced by GN to declare the dependency (and this will propagate
libyuv_config).

      ARGBToAR30 use vpmulhuw to replicate fields · 11dd1b95
      Frank Barchard authored 
      AR30 is optimized with 3 techniques
1. vpmulhuw is used to replicate 8 bits to 10 bits.
2. Two channels are processed at a time.  R and B, and A and G.
3. vpshufb is used to shift and mask 2 channels of R and B

Red Blue
With the 8 bit value in the upper bits, vpmulhuw by (1024+4) will produce a 10
bit value in the low 10 bits of each 16 bit value. This is whats wanted for the
blue channel. The red needs to be shifted 4 left, so multiply by (1024+4)*16 for
red.

Alpha Green
Alpha and Green are already in the high bits so vpand can zero out the other
bits, keeping just 2 upper bits of alpha and 8 bit green. The same multiplier
could be used for Green - (1024+4) putting the 10 bit green in the lsb.  Alpha
would be a simple multiplier to shift it into position.  It wants a gap of 10
above the green.  Green is 10 bits, so there are 6 bits in the low short.  4
more are needed, so a multiplier of 4 gets the 2 bits into the upper 16 bits,
and then a shift of 4 is a multiply of 16, so (4*16) = 64.  Then shift the
result left 10 to position the A and G channels.

      Convert16To8Row_SSSE3 port from AVX2 · 324fa327
      Frank Barchard authored 
      H010ToAR30 uses Convert16To8Row_SSSE3 to convert 10 bit YUV to 8 bit.
Then standard YUV conversion can be used.  This improves performance
on low end CPUs.
Future CL will by pass this conversion allowing for 10 bit YUV source,
but the function will be useful as a utility for YUV conversions.
