Some tests assume that iteration through an unordered multiset elements will return them in the same order as at the container creation. This assumption is not true since the container is unordered, so that no specific order of elements is ever guaranteed for such container. This patch introduces checks verifying that any iteration will return elements exactly from a set of valid values and without repetition, but in no particular order. Thanks to Andrey Maksimov for the patch. Differential Revision: https://reviews.llvm.org/D56500 git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@361494 91177308-0d34-0410-b5e6-96231b3b80d8
