	* einfo.adb Flag301 is now known as Ignore_SPARK_Mode_Pragmas.
	(Ignore_SPARK_Mode_Pragmas): New routine.
	(Set_Ignore_SPARK_Mode_Pragmas): New routine.
	(Write_Entity_Flags): Add an entry for Ignore_SPARK_Mode_Pragmas.
	* einfo.ads Add new attribute Ignore_SPARK_Mode_Pragmas and update
	related entities.
	(Ignore_SPARK_Mode_Pragmas): New routine
	along with pragma Inline.
	(Set_Ignore_SPARK_Mode_Pragmas): New routine along with pragma Inline.
	* opt.ads Rename flag Ignore_Pragma_SPARK_Mode to
	Ignore_SPARK_Mode_Pragmas_In_Instance.
	* sem_ch6.adb (Analyze_Subprogram_Body_Helper):
	Save and restore the value of global flag
	Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
	of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
	the corresponding spec or the body must ignore all SPARK_Mode
	pragmas found within.
	(Analyze_Subprogram_Declaration): Mark
	the spec when it needs to ignore all SPARK_Mode pragmas found
	within to allow the body to infer this property in case it is
	instantiated or inlined later.
	* sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
	value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
	the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
	when the corresponding spec also ignored all SPARK_Mode pragmas
	found within.
	(Analyze_Package_Declaration): Mark the spec when
	it needs to ignore all SPARK_Mode pragmas found within to allow
	the body to infer this property in case it is instantiated or
	inlined later.
	* sem_ch12.adb (Analyze_Formal_Package_Declaration):
	Save and restore the value of flag
	Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
	formal spec when it needs to ignore all SPARK_Mode
	pragmas found within to allow the body to infer this
	property in case it is instantiated or inlined later.
	(Analyze_Package_Instantiation): Save and restore the value
	of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
	the instance spec when it needs to ignore all SPARK_Mode
	pragmas found within to allow the body to infer this
	property in case it is instantiated or inlined later.
	(Analyze_Subprogram_Instantiation): Save and restore the value
	of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
	instance spec and anonymous package when they need to ignore
	all SPARK_Mode pragmas found within to allow the body to infer
	this property in case it is instantiated or inlined later.
	(Instantiate_Package_Body): Save and restore the value of global
	flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of
	global flag Ignore_SPARK_Mode_Pragmas_In_Instance when the
	corresponding instance spec also ignored all SPARK_Mode pragmas
	found within.
	(Instantiate_Subprogram_Body): Save and restore the
	value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
	the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
	when the corresponding instance spec also ignored all SPARK_Mode
	pragmas found within.
	* sem_prag.adb (Analyze_Pragma): Update the reference to
	Ignore_Pragma_SPARK_Mode.
	* sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
	all SPARK_Mode pragmas defined within yields mode "off".
