These new members need to be defined in Debug Mode, because the
iterators passed in as hints and returned as results need to be safe
iterators.
No new tests, because we already have tests for these members, and
they're failing in debug mode.
Tested powerpc64le-linux, committed to trunk.
commit ae899df9056ff8a58d658ef42125935856503f96
Author: Jonathan Wakely <jwak...@redhat.com>

try_emplace and insert_or_assign for Debug Mode.
* include/debug/map.h (map::try_emplace, map::insert_or_assign):
Define.
* include/debug/unordered_map (unordered_map::try_emplace,
unordered_map::insert_or_assign): Define.
