P1008R1 - prohibit aggregates with user-declared constructors
* class.c (check_bases_and_members): For C++2a set
CLASSTYPE_NON_AGGREGATE based on TYPE_HAS_USER_CONSTRUCTOR rather than
type_has_user_provided_or_explicit_constructor.
* g++.dg/ext/is_aggregate.C: Add tests with deleted or defaulted ctor.
* g++.dg/cpp0x/defaulted1.C (main): Ifdef out for C++2a B b = {1};.
* g++.dg/cpp0x/deleted2.C: Expect error for C++2a.
* g++.dg/cpp2a/aggr1.C: New test.
* g++.dg/cpp2a/aggr2.C: New test.
