From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>
We'll switch to adding the 'struct cu' instance to the 'struct cus' list
early, under the lock, to keep the order from the original DWARF file
and then LSK_KEEPIT will just leave it there while LSK_DELETE will first
remove it from the cus list, under cus lock, to then call cu__delete().
