Subject: [Ada] Consistent tree decoration to import C++ classes

For consistency, entity Ada.Tags.Prim_Ptr must be decorated with
attribute Is_Dispatch_Table_Entity to help the backend generating
code for dispatching calls. This decoration was missing in CPP_Types
thus causing problems in some architectures (for example, IA-64/Linux).

Tested on x86_64-pc-linux-gnu, committed on trunk

2012-07-17  Javier Miranda  <miranda@adacore.com>

	* exp_disp.adb (Make_DT): Remove decoration of Ada.Tags entities.
	(Make_Tags): Add decoration of Ada.Tags entities.
