	* sem_disp.adb (Check_Dispatching_Call): Major rewriting to
	handle some complex cases of tag indeterminate calls that are
	actuals in other dispatching calls that are themselves tag
	indeterminate.
	(Check_Dispatching_Context): Add parameter to support recursive
	check for an enclosing construct that may provide a tag for a
	tag-indeterminate call.

	* sem_prag.adb (Analyze_Depends_In_Decl_Part):
	Add global variables Task_Input_Seen and Task_Output_Seen.
	(Analyze_Global_Item): Detect an illegal use of the current
	instance of a single protected/task type in a global annotation.
	(Analyze_Input_Output): Inputs and output related to the current
	instance of a task unit are now tracked.
	(Check_Usage): Require
	the presence of the current instance of a task unit only when
	one input/output is available.	(Current_Task_Instance_Seen):
	New routine.
	(Is_CCT_Instance): New parameter profile. Update
	the comment on usage. The routine now properly recognizes several
	cases related to single protected/task types.

	* freeze.adb (Freeze_Entity): Use New_Freeze_Node
	to create a brand new freeze node. This handles a case where an
	ignored Ghost context is freezing something which is not ignored
	Ghost and whose freeze node should not be removed from the tree.
	(New_Freeze_Node): New routine.

	* sigtramp.h (__gnat_set_is_vxsim) New function to
	tell sigtramp-vxworks to handle vxsim signal contexts.	*
	sigtramp-vxworks.c (__gnat_sigtramp) Take into account the
	differences in the sigcontext structure between the expected
	regular x86 or x86_64 ones and the ones received in case of
	exexution on the vxworks simulator.
	* init.c: also compute is_vxsim in case of x86_64-vx7 target. Provide
	this information to sigtramp-vxworks.c. Remove the old mechanism for
	vxsim.
	* init-vxsim.c, sigtramp-vxworks-vxsim.c: remove, now obsolete.

	* exp_ch3.adb (Inline_Init_Proc): New function returning
	whether the initialization procedure of a type should be
	inlined.  Return again True for controlled type themselves.
	(Build_Array_Init_Proc): Call it to set Set_Is_Inlined on Init_Proc.
	(Build_Record_Init_Proc): Likewise.
