[Ada] Fix crash on type extensions with discriminants

Browse Source 
gcc/ada/

	* exp_put_image.adb (Make_Component_Attributes): Use
	Implementation_Base_Type to get the parent type. Otherwise,
	Parent_Type_Decl is actually an internally generated subtype
	declaration, so we blow up on
	Type_Definition (Parent_Type_Decl).
