COMP: Fix problem with narrowing in c++11
...
modules/core/src/arithm.cpp:345:51:
error: constant expression evaluates to 4294967295 which cannot be narrowed to type 'int' [-Wc++11-narrowing]
static int CV_DECL_ALIGNED(16) v64f_absmask[] = { 0xffffffff, 0x7fffffff, 0xffffffff, 0x7fffffff };
^~~~~~~~~~
Converted to unsigned int. This variable is only used to initialize a bit pattern anywhy for a 128bit type.

perspectiveTransform simplify assert() for better debuggin
...
When using perspectiveTransform in rather complicated settings, it would be easier for developers to have two separate assertions for each part of the boolean expression in order to pinpoint problems more efficiently. In my case I am struggling in Python2.7 with finding out whether scn+1 == m.cols or the depth == CV_32F || depth == CV_64F is making a problem, which is kind of hard.

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).
