This is the library fix for PR103520 that also prevents the garbage
collector from releasing live memory. However this requires that the
host compiler has been patched with this fix, so the GC will remain
disabled in the D front-end for now until enough time has passed for
this to have trickled down into enough releases.
libphobos/ChangeLog:
* libdruntime/core/thread/osthread.d (callWithStackShell): Push all
callee-save registers on the stack for AArch64 and ARM.
