This adds additional tests for std::map and std::multimap CTAD. The tests ensure that deduction works for braced-init-list of value_type objects, and for pairs of input iterators (with both std::pair<Key, T> and value_type as the iterator's value_type). This ensures deduction from value_type still works, as well as the non-value_type cases in LWG 3025. Similar tests for unordered maps do not work, apparently because the constructor taking an initializer_list<value_type> is not usable for deduction, and the deduction guide taking initializer_list<pair<Key, T>> deduces key_type to be const. I am not addressing that. * testsuite/23_containers/map/cons/deduction.cc: Test deduction from initializer_list<value_type> and from input iterator ranges. * testsuite/23_containers/multimap/cons/deduction.cc: Likewise.
