[Ada] Fix internal error on subprogram instantiation

Browse Source 
The compiler builds renamings for actuals of formal objects for debugging
purposes in this case, but it must not generate them for temporaries.

gcc/ada/

	* exp_dbug.ads (Build_Subprogram_Instance_Renamings): Fix typo.
	* exp_dbug.adb (Build_Subprogram_Instance_Renamings): Build the
	renaming only for actuals of formal objects.
