Fixed several problems found by PVS-Studio.
...
This fixes all problems from the article "Checking OpenCV with PVS-Studio"
<http://www.viva64.com/en/b/0191/ > that are not already fixed and are
not in 3rdparty or the legacy module.
The problems fixed are two instances of useless code and one instance
of unspecified behavior (right-shifting a negative number).

Implimentation "cv::Mat::forEach"
...
I propose forEach method for cv::Mat and cv::Mat_.
This is solution for the overhead of MatIterator_<_Tp>.
I runs a test that micro opecode runs all over the pixel of cv::Mat_<cv::Point3_<uint8_t>>.
And this implementation 40% faster than the simple pointer, 80% faster than iterator.
With OpenMP, 70% faster than simple pointer, 95% faster than iterator (Core i7 920).
Above all, code is more readable.
My test code is here.
