Add MSA optimized I422ToARGBRow_MSA and I422ToRGBARow_MSA functions
R=fbarchard@google.com
BUG=libyuv:634
Performance Gains :- (vs C vectorized)
I422ToARGBRow_MSA : ~1.6x
I422ToRGBARow_MSA : ~1.6x
I422ToARGBRow_Any_MSA : ~1.58x
I422ToRGBARow_Any_MSA : ~1.6x
Performance Gains :- (vs C non-vectorized)
I422ToARGBRow_MSA : ~7x
I422ToRGBARow_MSA : ~7x
I422ToARGBRow_Any_MSA : ~6.9x
I422ToRGBARow_Any_MSA : ~6.8x
Regarding performance measurement, We have created standalone tests which pass in row's data from a 1920x1080 filled buffer to both the C and MSA functions. And such N iterations are executed to get more accurate timings of C vs MSA.
