Frank Barchard bad52cccd6 [libyuv] Add NEON implementations for all remaining C row functions ... Implement 32-bit and 64-bit Arm NEON versions (in row_neon.cc and row_neon64.cc) for the 12 remaining row functions that previously fell back to C on Arm: - AR30ToAB30Row_NEON (and AR30ToAB30Row_Any_NEON) - AR30ToABGRRow_NEON (and AR30ToABGRRow_Any_NEON) - AR30ToARGBRow_NEON (and AR30ToARGBRow_Any_NEON) - ARGBAffineRow_NEON - ARGBColorTableRow_NEON - ARGBCopyAlphaRow_NEON (and ARGBCopyAlphaRow_Any_NEON) - ARGBLumaColorTableRow_NEON - ARGBPolynomialRow_NEON (and ARGBPolynomialRow_Any_NEON) - ARGBUnattenuateRow_NEON (and ARGBUnattenuateRow_Any_NEON) - CopyRow_16_NEON (and CopyRow_16_Any_NEON) - MirrorRow_16_NEON (and MirrorRow_16_Any_NEON) - RGBColorTableRow_NEON Add HAS_*_NEON macros, prototypes, _Any wrappers, NEON dispatches in convert.cc, convert_argb.cc, and planar_functions.cc, and enable unit tests in planar_test.cc. Arm row function SIMD coverage is now 164/164 (100%).
