    lto/106334 - relax assert during WPA tree merging

    The dwarf2out map of tree to symbol + offset is populated too early
    when streaming in trees so that when WPA tree merging decides to
    recycle them the mapping prevails and if we are unlucky the same
    address is used for another tree with a symbol + offset DIE to
    record.  The following mitigates the resulting ICE by relaxing the
    assert, allowing re-use of a slot during WPA.  Delaying the register
    would be better but it's already somewhat hairy and uglifying this
    further doesn't look too important right now.

            PR lto/106334
            * dwarf2out.cc (dwarf2out_register_external_die): Allow
            map entry re-use during WPA.=
