Catch exceptions by const-reference
...
Exceptions caught by value incur needless cost in C++, most of them can
be caught by const-reference, especially as nearly none are actually
used. This could allow compiler generate a slightly more efficient code.

imgproc:simd Enable VSX and wide universal intrinsics for accumulate operations
...
- improve cpu dispatching calls to allow more SIMD extentions
(SSE4.1, AVX2, VSX)
- wide universal intrinsics
- replace dummy v_expand with v_expand_low
- replace v_expand + v_mul_wrap with v_mul_expand for product accumulate operations
- use FMA for accumulate operations
- add mask and more types to accumulate's performance tests

Change behaviour of 16-bit multiply operator
...
- redefine 16-bit multiply operator to perform saturating multiply
instead of non-saturating multiply
- implement 8-bit multiply operator to perform saturating multiply
- implement v_mul_wrap() for 8-bit, 16-bit non-saturating multiply
- improve performance of v_mul_hi() for VSX
- update intrin tests with new changes
- replace unv 16-bit multiplication operator with v_mul_wrap due behavior changes
- Several improvements depend on vpisarev review
* initial forward declarations for universal intrinsics
* move emulating SSE intrinsics into separate file
* implement v_mul_expand for 8-bit
* reimplement saturating multiply using v_mul_expand + v_pack
* map v_expand, v_load_expand, v_load_expand_q to sse4.1
* fix overflow avx2::v_pack(uint32)
* implement two universal intrinsics v_expand_low and v_expand_high
