remove raw SSE2/NEON implementation from imgwarp.cpp

Browse Source 
* use universal intrinsic instead of raw intrinsic
  * add 2 channels de-interleave on x86 platform
  * add v_int32x4 version of v_muladd
  * add accumulate version of v_dotprod based on the commit from seiko2plus on bf1852d
  * remove some verify check in performance test
  * avoid the out of boundary access and keep the performance
