The expected cxa_atexit calls and optimizations won't take place on
targets that don't have -fuse-cxa-atexit enabled by default. Enabling
it explicitly is enough to meet the expectations of the cxa_atexit
tests.
Regstrapped on x86_64-linux-gnu. Also tested with aarch64-elf and
arm-eabi with gcc-15. Ok to install?
for gcc/testsuite/ChangeLog
* g++.dg/tree-ssa/cxa_atexit-1.C: Enable -fuse-cxa-atexit.
* g++.dg/tree-ssa/cxa_atexit-2.C: Likewise.
* g++.dg/tree-ssa/cxa_atexit-3.C: Likewise.
* g++.dg/tree-ssa/cxa_atexit-4.C: Likewise.
* g++.dg/tree-ssa/cxa_atexit-5.C: Likewise.
* g++.dg/tree-ssa/cxa_atexit-6.C: Likewise.

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
