* s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
in general and triggers stack alignment adjustment for thread entry
points on targets where this is necessary.

* init.c (__gnat_initialize): Call an Ada subprogram to perform the
table registration calls when need be. Ensures no reference to the crt
ctors symbol are issued in the SJLJ case, which avoids possible
undefined symbol errors in the case of modules to be statically linked
with the kernel.

* sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
in-line the code corresponding to subprogram Analyze_Actuals. In
addition, analyze the actuals only in case of subprogram call.

* exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
consider expressions buried within a procedure actual to be an actual.
This caused some blowups with uses of packed slices within a procedure
actual.

* exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
longer need to be initialized to zero.
(Get_Simple_Init_Val): Modular packed arrays no longer need to be
initialized to zero.
* checks.adb (Expr_Known_Valid): Packed arrays are now always
considered valid, even if the representation is modular. That's correct
now that we no longer initialize packed modular arrays to zero.
* exp_dbug.ads: Clarify documentation on handling of PAD and JM
suffixes. These are now documented as the only cases in which the
debugger ignores outer records.
Previously, the spec allowed arbitrary suffixes for this purpose.
Change name of LJM to JM for packed array pad records
Create separate section on packed array handling, and add a whole new
set of comments to this section describing the situation with packed
modular types and justification requirements depending on endianness.

* sem_ch12.adb (Check_Generic_Actuals): New predicate
Denotes_Previous_Actual, to handle properly the case of a private
actual that is also the component type of a subsequent array actual.
The visibility status of the first actual is not affected when the
second is installed.
(Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
make fully recursive the treatment of formals of packages declared
with a box.
(Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
the above on exit from an instantiation.
(Denotes_Formal_Package): When called from Restore_Private_Views, ignore
current instantiation which is now complete.
(Analyze_Package_Instantiation): No instantiated body is needed if the
main unit is generic. Efficient, and avoid anomalies when a instance
appears in a package accessed through rtsfind.

* sem_util.adb (Explain_Limited_Type): Ignore internal components when
searching for a limited component to flag.
* exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
expansion of Input, to account for the fact that the implicit call
generated by the attribute reference must freeze the user-defined
stream subprogram. This is only relevant to 'Input, because it can
appear in an object declaration, prior to the body of the subprogram.
* sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
expansion can proceed and further errors uncovered.
(Minor clean up): Fix cases of using | instead of \ for continuation
messages.

underlying operating system at run time (when False).
It is initially set to False in all targets.
* exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack

Minor reformatting for better alignment with PolyORB version.
