This patch is for the ocl module of 2.4.3

(tested on Mac (OSX 10.8, Xcode 4.5, OpenCL 1.1(?))

added support armv7s for iOS framework; tested on my computer (OSX 10.8, Xcode 4.5)

remove as much warnings as possible
use enum instead of MACRO for ocl.hpp
add command line parser in accuracy test and perf test
some bug fix for arthim functions

After setting depth to CV_32F for non double types this produces difference in results. I've attached test that reproduce this issue.The issue was found during anali broken GPU tests  for multiply/device functions.

Add output stream operators (<<) for Rect, Size, Matx, Vec.
I can't add operations for cv::KeyPoint.

And putting together all operator<<.
(Matx, Point_, Point3_, Vec, Size_, Rect_)
