decl.c (init_decl_processing): Reenable inlining on trees.
* decl.c (init_decl_processing): Reenable inlining on trees.
(finish_function): Likewise.
* expr.c (cplus_expand_expr): Don't handle AGGR_INIT_EXPR here.
* semantics.c (simplify_aggr_init_exprs): New function.
(expand_body): Use it.
* tree.c (walk_tree): Special-case TARGET_EXPRs since they
sometimes present the same sub-tree twice.
