* init.c (build_default_init): New fn.
(perform_member_init): Split out from here.
(build_new_1): Use it. Simplify initialization logic.
(build_vec_init): Take an array, rather than a pointer and maxindex.
Speed up simple initializations. Don't clean up if we're assigning.
* cp-tree.h: Adjust.
* decl2.c (do_static_initialization): Remove TREE_VEC case.
* parse.y (new_initializer): Return void_zero_node for ().
* typeck.c (build_modify_expr): Handle getting a CONSTRUCTOR.
* typeck2.c (digest_init): Only complain about user-written
CONSTRUCTORs.
