	* sem_res.adb (Static_Concatenation): An N_Op_Concat with static
	operands is static only if it is a predefined concatenation operator.

	* sem_util.adb: Minor reformatting

	* sem_ch12.adb (Save_References): When propagating semantic information
	from generic copy back to generic template, for the case of an
	identifier that has been rewritten to an explicit dereference whose
	prefix is either an object name or a parameterless funcion call
	denoting a global object or function, properly capture the denoted
	global entity: perform the corresponding rewriting in the template,
	and point the rewritten identifier to the correct global entity (not
	to the associated identifier in the generic copy).
