[Ada] Management of internal data structures in Sem_Elab
This patch modifies the timing of Sem_Elab's internal data structure
creation and destruction, and adds the concept of "active" elaboration
compiler phase.
The elaboration phase of the compiler is active after the frontend
initializes Sem_Elab. It is at this point that all internal data
structures of Sem_Elab are created and become ready to accept data.
The elaboration phase of the compiler is completed after all elaboration
scenarios are examined, all ABE checks are intalled, and diagnostics are
emitted. It is at this point that all internal data structures of
Sem_Elab are destroyed. Further attempts to reintroduce data into
Sem_Elab by subsequent compiler phases are cut off.
Compilation using GCC unaffected.

The compiler prematurely freezes a private type that is the type of a

The library handling and some of the options for creating the crts for
the older PPC Darwin versions had bit-rotted somewhat. This adjusts the

compiler: include transitive imports in the type descriptor list
In CL 179598, we were using Gogo::packages_, when compiling the
main package, as the list of packages of which we need to
register the type descriptors. This is not complete. It only
includes main's direct import and one-level indirect imports. It
does not include all the packages transitively imported.
To fix that, we need to track all the transitive imports. We
have almost already done that, for init functions. However, there
may be packages that don't need init functions but do need to
register type descriptors. For them, we add a dummy init function
to its export data. So when we compile the main package we will
see all the transitive imports. The dummy init functions are not
real functions and are not called.
Fixes golang/go#32901.

[aarch64]: force frame pointer setup before tlsdesc call
The operation that sets up the tlsdesc register is really a function
call; as such, the frame pointer should really be correctly set up
before this happens. However, because it does not appear as a
call_insn in the RTL the normal dependencies are not added
automatically. We fix this by adding a USE of FP_REGNUM to prevent
migration of the frame-pointer setup past the call by the scheduler.
If a frame pointer is not being used, this is harmless since it only
represents a scheduling constraint.

[Ada] ABE checks v3.0, foundations of Elaboration order v4.0
------------------------
-- Elaboration checks --
------------------------
The dynamic ABE checks model now emits the same diagnostics as those of the
static ABE checks model.
The ABE checks mechanism has been redesigned and refactored in the face of
increasing requirements. Most of the functionality can now be toggled, thus
allowing for various combinations of behavior. The combinations are defined
as "initial states" and may be further altered.
Scenarios and targets have been distinctly separated at the higher level,
instead of directly working with nodes and entitites. Scenarios and targets
now carry a representation which removes the need to constantly recompute
relevant attributes, and offers a common interface for the various processors.
Most processing has now been refactored into "services" which perform a single
ABE-related function.
-----------------------
-- Elaboration order --
-----------------------
A new elaboration order mechanism based on the use of an invocation graph to
provide extra information about the flow of execution at elaboration time has
been introduced.
The ABE checks mechanism has been altered to encode pieces of the invocation
graph in the associated ALI files of units.
The new elaboration order mechanism reconstructs the full invocation graph at
bind time, and coupled with the library item graph, determines the elaboration
order of units.
The new elaboration order mechanism is currently inaccessible.

[Ada] Make loop labels unique for front-end inlined calls
This patch transforms loop labels in the body of subprograms that are to
be inlined by the front-end, to prevent accidental duplication of loop
labels, which might make the resulting source illegal.

compiler: rework type and package tracking in exporter
Revamps the way the exporter tracks exported types and imported
packages that need to be mentioned in the export data.
The previous implementation wasn't properly handling the case where an
exported non-inlinable function refers to an imported type whose
method set includes an inlinable function whose body makes a call to a
function in another package that's not directly used in the original
package.
This patch integrates together two existing traversal helper classes,
"Collect_references_from_inline" and "Find_types_to_prepare" into a
single helper "Collect_export_references", so as to have common/shared
code that looks for indirectly imported packages.
