[Ada] Spurious error on overloaded equality in postcondition

This patch fixes a spurious error in a postcondition in a nested
instantiation when the expression includes an inherited equality and
checks are enabled.

* sem_res.adb (Resolve_Equality_Op): Do not replace the resolved
operator by its alias if expander is not active, because the
operand type may not be frozen yet and its inherited operations
have not yet been created.

[Ada] Elaboration order v4.0 and linker switches

This patch adds a missing functionality with respect to elaboration
order v3.0.  Units carry an attribute called Elab_Position which among
other things controls the sorting of linker switches by gnatbind.
Setting the proper position ensures the gnatbind will output the linker
switches in an order compatible with what gnatlink expects.

No simple test available as this requires a Windows cross-compiler.

[Ada] Use renamings in GNATprove mode for side-effects extraction

In the GNATprove mode for formal verification, prefer renamings over
declaration of a constant to extract side-effects from expressions,
whenever the constant could be of an owning type, as declaring a
constant of an owning type has an effect on ownership which is
undesirable.

There is no impact on compilation.

[aarch64]: redefine aes patterns

This first patch removes aarch64 usage of the aese/aesmc and aesd/aesimc
fusions (i.e. aes fusion) implemented in the scheduler due to unpredictable
behaviour observed in cases such as:
- when register allocation goes bad (e.g. extra movs)
- aes operations with xor and zeroed keys among interleaved operations

A more stable version should be provided by instead doing the aes fusion
during the combine pass. Since the aese and aesd patterns have been
rewritten as encapsulating a xor operation, the existing combine fusion
patterns have also been updated. The purpose is to simplify the need of
having additional combine patterns for cases like the ones below:

For AESE (though it also applies to AESD as both have a xor operation):

    data = data ^ key;
    data = vaeseq_u8(data, zero);
    ---
    eor         v1.16b, v0.16b, v1.16b
    aese        v1.16b, v2.16b

Should mean and generate the same as:

    data = vaeseq_u8(data, key);

[arm]: redefine aes patterns

This patch removes the arch-common aese/aesmc and aesd/aesimc fusions
(i.e. aes fusion) implemented in the scheduling phase through the
aarch_crypto_can_dual function. The reason is due to observing
undesired behaviour in cases such as:
- when register allocation goes bad (e.g. extra movs)
- aes operations with xor and zeroed keys among interleaved operations

A more stable version should be provided by instead doing the aes fusion
during the combine pass. As such, new combine patterns have been added to
enable this.

The second change is the aese and aesd patterns have been rewritten as
encapsulating a xor operation. The purpose is to simplify the need of
having additional combine patterns for cases like the ones below:

For AESE (though it also applies to AESD as both have a xor operation):

This patch enhances the compiler to add an optional warning for

runtime accessibility checks that they generate. For more details see RM
3.10.2 sections 14/3, 14.1/3, and 14.2/3.

These warnings can now be enabled with -gnatw_a, disabled with -gnatw_A
and are part of the "all warnings" flag -gnatwa.

[Ada] Crash/infinite loop on program with multiple visibility errors

This patch fixes the behavior of the compiler on a program with multiple
visibility errors. Previous to this fix the compiler would either crash
or enter an infinite loop on a declaration for the formal in a
subprogram declaration, when the parameter type was given by a selected
component that does not denote an entity. This patch also specializes
the error message when a local overloadable name has a homonym that is a
child package, which may containt an otherwise hidden interpreatation.

[Ada] Elaboration order v4.0 and generic instantiations

This patch updates the library graph augmentation mechanism of the

the invocation edge from the instance to the generic body is not
considered for library graph augmentation.

CommandLineToArgvW drags a dependency on SHELL32.DLL and thus GDI32.DLL.

[Ada] New algorithm for Elaboration order v4.0

This patch introduces several changes to the new elaboration order
mechanism:

   * The concept of "strong" and "weak" edges is introduced. Strong
     edges are the byproduct of language-defined relations between
     units, such as with clauses. Weak edges are the byproduct of
     specilative invocations at elaboration time, which may or may not
     take place depending on control flow.

   * The elaboration order algorithm has been heavily modified to make
     use of the strong and weak edges, and operate on units compiled
     with different elaboration models.

   * The elaboration order algorithm employs the following logic:

        - Maintain two sets of vertices, one for all elaborable
          vertices, and one for all waiting vertices.

        - Pick the best elaborable vertex, and elaborate its component.

        - If no such elaborable vertex is available, pick the best
          weakly elaborable vertex whose unit has been compiled with the
          dynamic model, and elaborate its component.

        - If no such weakly elaborable vertex is available, then either
          all vertices were already elaborated, or the graph contains a
          cycle.

     The elaboration of a component employs the same logic, with an
     added step where all successors of some predecessor currently being
     elaborated are notified that they have one fewer predecessor to
     wait on. This may cause certain successors to become elaborable, in
     which case they are moved from the set of waiting vertices to the
     set of elaborable vertices.

   * Three new GNATbind debug switches are introduced, -d_a, -d_b, and
     -d_e, to eliminate the effects of pragmas Elaborate_All,
     Elaborate_Body, and Elaborate respectively.

   * The section on terminology is updated to include new entries.

elab code away from gcov's analysis, a regression compared to previous

[Ada] Fix crash on extension of private type with -gnatRj

This fixes a crash (or an assertion failure) during the processing done
for -gnatRj on the declaration of an extension of a private type.
Generally speaking, extension declarations are delicate in this context
because the front-end does not duplicate the structure of the parent
type, so the processing required to output the structural layout needs
to go up to the declaration of the parent type, which may or may not be
available or usable.

The change also makes the processing more robust by falling back to the
flat layout if the declaration of the parent type cannot be processed.
