re PR debug/34037 (Bounds for VLAs not emitted into debuginfo)
PR debug/34037
* gimplify.c (gimplify_type_sizes): When not optimizing, ensure
TYPE_MIN_VALUE and TYPE_MAX_VALUE is not is not DECL_IGNORED_P
VAR_DECL.
* cfgexpand.c (expand_used_vars): Keep DECL_ARTIFICIAL
!DECL_IGNORED_P vars in local_decls list for instantiate_decls,
ggc_free other TREE_LIST nodes from that chain.
* function.c (instantiate_decls): Instantiate also DECL_RTL
of vars in cfun->local_decls, free that list afterwards.
