New Revision: 16249
Remove arm64 specific (unused) setup_child () and assign_guest_tls ().
valgrind svn r16186 (which fixed bug #342040 and #373192) introduced a
generic linux way of handling setup_child and assign_guest_tls. So there
is no need anymore for arch specific implementations. And gcc complained
they were unused.
