9e61a28b2e Improve canny (#7227)
* Improve Canny by using _mm_movemask_epi8 to find next pixel magnitude greater than lower threshold. Added parallelized finalPass to Canny with variable gradients. Little changes in finalPass.

* Some things fixed

7fef96be1e add 64F intrinsic in HAL NEON
* use universal intrinsic for accumulate series using float/double
  * accumulate, accumulateSquare, accumulateProduct and accumulateWeighted
  * add v_cvt_f64_high in both SSE/NEON
  * add test for conversion v_cvt_f64_high in test_intrin.cpp
  * improve some existing universal intrinsic by using new instructions in Aarch64
  * add workaround for Android build in intrin_neon.hpp

5ddd25313f Add Grana's connected components algorithm for 8-way connectivity. (#6823)
* Add Grana's connected components algorithm for 8-way connectivity. That algorithm is faster than Wu's one (currently implemented in opencv). For more details see https://github.com/prittt/YACCLAB.

* New functions signature and distance transform compatibility

* Add tests to imgproc/test/test_connectedcomponents.cpp

* Change of test_connectedcomponents.cpp for c++98 support

ba73249dc0 let the test of AccSqr_SIMD<ushort, float> pass
* The difference becomes too large when multiply is done in int16
  * To reproduce the test failure, IPP has to be switched off

b8e08d5d3c ocl: fix Canny for Intel devices
There is an issue with processing of abs(short) function for
negative argument.

Affected OpenCL devices:

5f30a0a076 Merge pull request #6958 from mschoeneck:Common-Canny-parallelization
* Common Canny parallelization added. TBB and single thread code removed. Final pass vectorized with SSE2 intrinsics.

* wrong #ifdef replaced with #if

* Merged to actual Canny version

* Merged common parallelized Canny with actual Canny implementation

* Remove 'Mutex *mutex' and pass 'Mutex mutex' from outside to parallelCanny

* Replaced extern Mutex with intern mutable Mutex.
