Implement P1816R0, class template argument deduction for aggregates.
Rather than reimplement brace elision here, we call reshape_init and then
discard the result. We needed to set CLASSTYPE_NON_AGGREGATE a bit more in
this patch, since outside a template it's set in check_bases_and_members.
* pt.c (maybe_aggr_guide, collect_ctor_idx_types): New.
(is_spec_or_derived): Split out from do_class_deduction.
(build_deduction_guide): Handle aggregate guide.
* class.c (finish_struct): Set CLASSTYPE_NON_AGGREGATE in a
template.
* cp-tree.h (CP_AGGREGATE_TYPE_P): An incomplete class is not an
aggregate.
