The fix for PR c++/52637 slightly broke the handling of local types in Ada.
The attached patch restores correct generation of debug info for them.

Tested on i586-suse-linux, applied on mainline and 4.7 branch.

	* gcc-interface/utils.c (gnat_pushdecl): Set TYPE_CONTEXT for types
	attached to a TYPE_DECL.
