    Merge pull request #12411 from vpisarev:wide_convert · 80b62a41
    Vadim Pisarevsky authored
    * 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
