[patch] Introduce DECL_NONLOCAL_FRAME

[Eric Botcazou]

Hi,

this is the seemingly non-controversial part of the FRAME splitting patch.
It introduces the DECL_NONLOCAL_FRAME flag, sets it during nested function 
lowering and... that's pretty much it.

Tested on x86_64-suse-linux, OK for mainline?

        * tree.h (DECL_NONLOCAL_FRAME): New macro.
        * tree-nested.c (get_frame_type): Set DECL_NONLOCAL_FRAME.
        * tree-streamer-in.c (unpack_ts_decl_common_value_fields): Stream in
        DECL_NONLOCAL_FRAME flag.
        * tree-streamer-out.c (pack_ts_decl_common_value_fields): Stream out
        DECL_NONLOCAL_FRAME flag.
