asm: avx2 asm code for dct4
Cleaned up TComDataCU::getQuadtreeTULog2MinSizeInCU for clarity and a bit of performance
change index of m_buOffsetY[] from raster to zscan
TComDataCU: Reduced repeated function call to calculate depth range
x86asm: warn when inappropriate instruction used in function with specified cpuflags
count_nonzero primitive optimization, downscaling quantCoef from int32_t* to int16_t*
