[Ada] Stabilization of Elaboration order v4.0
This patch introduces several changes to the new elaboration order
mechanism:
* Instantiations processed in the context of invocation graph
encoding now yield a relation which is later transformed into an
invocation edge. This ensures that the unit where the instantiation
resides properly depends on the unit where the body of the generic
is.
* The diagnostics of cycles that involve invocation edges now use a
set to avoid infinite recursion when visiting paths that represent
recursive code.
* Various diagnostics that suggest the use of switches have been
updated to indicate which tool the switches apply to.
* Bindo can now output the dependencies of various units that specify
why a predecessor unit must be elaborated prior to a successor
unit. This functionality implements binder switch -e (output
complete list of elaboration order dependencies).
* The output of the elaboration order is now identical to that
emitted by Binde.
* The nature of the invocation graph encoding is now recorded in the
ALI record rather than the Unit record of a unit. This ensures that
both the spec and body share the same encoding kind.
* A section on debugging elaboration order issues is now available in
Bindo.

* The elaboration order mechanism can now diagnose one or all cycles

This patch modifies the timing of Sem_Elab's internal data structure

The elaboration phase of the compiler is active after the frontend
initializes Sem_Elab. It is at this point that all internal data

The elaboration phase of the compiler is completed after all elaboration
scenarios are examined, all ABE checks are intalled, and diagnostics are
