[COMMITTED] ada: Add typedefs to snames.h-tmpl

[COMMITTED] ada: Add typedefs to snames.h-tmpl

[Marc Poulhiès]

From: Tom Tromey <tromey@adacore.com>

A future patch will change sname.h-tmpl to use enums rather than
preprocessor defines.  In order to do this, first introduce some
typedefs that can be used in gcc-interface.

gcc/ada/

	* snames.h-tmpl (Name_Id, Attribute_Id, Convention_Id)
	(Pragma_Id): New typedefs.
	(Get_Attribute_Id, Get_Pragma_Id): Use typedef.

Tested on x86_64-pc-linux-gnu, committed on master.
