[MemProf] Suppress duplicate clones in the LTO backend (#161551)
In some cases due to phase ordering issues with re-cloning during
function assignment, we may end up with duplicate clones in the
summaries (calling the same set of callee clones and/or allocation
hints).
Ideally we would fix this in the thin link, but for now, detect and
suppress these in the LTO backend. In order to satisfy possibly
cross-module references, make each duplicate an alias to the first
identical copy, which gets materialized.
This reduces ThinLTO backend compile times.
