	* debug.adb (d.D) reverve flag for the SPARK mode
	(d.E) reverve flag for SPARK generation mode
	(d.F) reverve flag for Why generation mode
	* opt.ads, opt.adb (ALFA_Mode, ALFA_Through_SPARK_Mode, 
	ALFA_Through_Why_Mode, Formal_Verification_Mode, SPARK_Mode):  New
	functions which return True when the corresponding modes are set
	(Formal_Language): return "spark" or "alfa" when in formal verification
	mode.
	* sem_util.ads, sem_util.adb (Formal_Error_Msg): new wrapper on
	Error_Msg to prefix the error message with a tag giving the formal
	language
	(Formal_Error_Msg_N): new wrapper on Error_Msg_N to prefix the error
	message with a tag giving the formal language
	* sem_ch5.adb (Analyze_Block_Statement): issue error in formal mode on
	block statement
	(Analyze_Case_Statement): issue error in formal mode on case statement
	with a single "others" case alternative
	(Analyze_Exit_Statement): issue errors in formal mode on exit
	statements which do not respect SPARK restrictions
	(Analyze_Goto_Statement): issue error in formal mode on goto statement
	(Check_Unreachable_Code): always issue an error (not a warning) in
	formal mode on unreachable code (concerns both code after an infinite
	loop and after an unconditional jump, both not allowed in SPARK)
	* sem_ch6.adb (Analyze_Return_Statement): add call to
	Set_Return_Present for a procedure containing a return statement
	(already done for functions in Analyze_Function_Return)
	(Analyze_Function_Return): issue error in formal mode on extended
	return or if return is not last statement in function
	(Check_Missing_Return): issue error in formal mode if function does
	not end with return or if procedure contains a return
	* sem_ch8.ads, sem_ch8.adb (Has_Loop_In_Inner_Open_Scopes): new
	function to detect if there is an inner scope of its parameter S which
	is a loop.
