I don't know what ZBarrierSetC2::matcher_find_shared_visit is meant to
do, never mind how it interacts with clone_address_expressions. However,
I don't see any problem having clone_address_expressions return false on
AArch64 when the address is being consumed by a LoadStore.
Anyway, what I really wanted to say was that the fix for the trailing
barrier lookup using an extra precedence link is a very nice, simple
