b2135be594 fast_math: add extra perf/unit tests 
Add a basic sanity test to verify the rounding functions
work as expected.

Likewise, extend the rounding performance test to cover the
additional float -> int fast math functions.

Merge pull request #14162 from alalek:eliminate_coverity_scan_issues 
core: eliminate coverity scan issues (#14162)

* core(hal): avoid using of r,g,b,a parameters in interleave/deinterleave

- static analysis tools blame on possible parameters reordering
- align AVX parameters with corresponding SSE/NEO/VSX/cpp code

* core: avoid "i,j" parameters in Matx methods

- static analysis tools blame on possible parameters reordering

* core: resolve coverity scan issues

1. someMatrix.data -> someMatrix.prt()
2. someMatrix.data + someMatrix.step * lineIndex -> someMatrix.ptr( lineIndex )
3. (SomeType*) someMatrix.data -> someMatrix.ptr<SomeType>()
4. someMatrix.data -> !someMatrix.empty() ( or !someMatrix.data -> someMatrix.empty() ) in logical expressions

7ea1bf3cf0 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).
