The fix affects follow algorithms:
remove_if, unique, rotate, inplace_merge, partial_sort_copy, set_union, set_intersection, set_difference, set_symmetric_difference.

1. For "is_trivial" types there are no problems with "creating objects/clean-up"
2. For non-trivial types the algo results are also correct, but possible incorrect copying/moving "operator="  calls "by raw memory" within one of mentioned algo or 	incorrect destructor calls in the end of algo.
