        * gimplify.c (declare_tmp_vars): Rename into declare_vars.
        Add debug_info parameter.  Chain the vars to the BLOCK instead
        of the BIND_EXPR if debug info are requested for them.
        (pop_gimplify_context): Adjust for above change.
        (gimple_add_tmp_var): Likewise.
        * tree-gimple.h (declare_tmp_vars): Rename into declare_vars.
        Add bool parameter.
        * tree-nested.c (convert_nonlocal_reference): Adjust for above change.
        (convert_local_reference): Likewise.
        (get_local_debug_decl): Set DECL_IGNORED_P on the original variable.
        (finalize_nesting_tree_1): Request that debug info be emitted
        for debug_var_chain.
