c++: copy location to AGGR_INIT_EXPR

When building an AGGR_INIT_EXPR from a CALL_EXPR, we shouldn't lose location
information.

gcc/cp/ChangeLog:

	* tree.cc (build_aggr_init_expr): Copy EXPR_LOCATION.

gcc/testsuite/ChangeLog:

	* g++.dg/cpp1y/constexpr-nsdmi7b.C: Adjust line.
	* g++.dg/template/copy1.C: Likewise.
