In _Safe_unordered_container the _M_invalidate_all and _M_invalidate_all_if
are made public to be used in nested struct _UContMergeGuard.
Thanks to friend declaration we can avoid those method to be accessible from
user code.
libstdc++-v3/ChangeLog:
* include/debug/safe_unordered_container.h
(_Safe_unordered_container::_UContInvalidatePred): Move outside class, at
namespace scope. Declare friend.
(_Safe_unordered_container::_UMContInvalidatePred): Likewise.
(_Safe_unordered_container::_UContMergeGuard): Likewise.
(_Safe_unordered_container::_M_invalidate_all): Make protected.
(_Safe_unordered_container::_M_invalidate_all_if): Likewise.
