* rewrote Mat::convertTo() and convertScaleAbs() to wide universal intrinsics; added always-available and SIMD-optimized FP16<=>FP32 conversion * fixed compile warnings * fix some more compile errors * slightly relaxed accuracy threshold for int->float conversion (since we now do it using single-precision arithmetics, not double-precision) * fixed compile errors on iOS, Android and in the baseline C++ version (intrin_cpp.hpp) * trying to fix ARM-neon builds * trying to fix ARM-neon builds * trying to fix ARM-neon builds * trying to fix ARM-neon builds
