[Ada] Enable Ada 2020 Put_Image and Image support for tagged types
gcc/ada/
* exp_put_image.adb: Eliminate references to
Debug_Flag_Underscore_Z. Change the meaning of the function
Enable_Put_Image. Previously, a result of False for a tagged
type would mean that the type does not get a Put_Image (PI)
routine at all. Now, it means that the type gets a PI routine
with very abbreviated functionality (just a call to
Unknown_Put_Image). This resolves problems in mixing code
compiled with and without the -gnat2022 switch.
* exp_ch3.adb: Enable_Put_Image no longer participates in
determining whether a tagged type gets a Put_Image procedure. A
tagged type does not get a Put_Image procedure if the type
Root_Buffer_Type is unavailable. This is needed to support cross
targets where tagged types are supported but the type
Root_Buffer_Type is not available.
* exp_dist.adb: Add workarounds for some problems that arise
when using the (obsolete?) Garlic implementation of the
distributed systems annex with Ada 2022 constructs.
* libgnat/a-sttebu.ads: Workaround a bootstrapping problem.
Older compilers do not support raise expressions, so revise the
the Pre'Class condition to meet this requirement without
changing the condition's behavior at run time.
