GC gdb/thread.c:current_thread_cleanup_chain
Commit 803bdfe43083475c7df3db38dc96f4e20d05457d ("Don't delete
thread_info if refcount isn't zero") eliminated
restore_current_thread_ptid_changed, so current_thread_cleanup_chain
is no longer necessary either.
gdb/ChangeLog:
2017-04-10 Pedro Alves <palves@redhat.com>
* thread.c (struct current_thread_cleanup) <next>: Delete field.
(current_thread_cleanup_chain): Delete.
(restore_current_thread_cleanup_dtor)
