This patch adds REGISTRY for struct address_space.

gdb:

2013-11-02 Yao Qi <yao@codesourcery.com>

* progspace.c: DEFINE_REGISTRY for address_space.
(new_address_space): Call address_space_alloc_data.
(free_address_space): Call address_space_free_data.
(struct address_space): Move it to ...
* progspace.h: ... here.
(struct address_space) <REGISTRY_FIELDS>: New.
Use DECLARE_REGISTRY.
