#12319: `boost::container::flat_set` should be nothrow move constructible

Milestone:  To Be Determined  |  Component:  container
  Version:  Boost 1.61.0      |   Severity:  Problem

------------------------------+------------------------
 It appears to me that in a simple oversight, `boost::container::flat_set`
 is missing a `noexcept` declaration on its move constructor.

 It is conditionally `noexcept` move assignable, assuming there are no
 allocator shenanigans.
 I'm not aware of a reason why something would be sometimes `noexcept` move
 assignable, but never move constructible.

 It appears to me that the implementation in fact does not throw, so I
 *believe* this could be fixed quite easily.

 It would help using this type with generic code in certain cases if it
 were marked thusly.
 Thank you.
