Adrian Prantl b29f9e5c41 dsymutil: Prune module forward decl DIEs if a uniquable definition was
already emitted and fix a latent bug in DIECloner where the DW_CHILDREN_yes
flag is set based on the number of children in the input DIE rather than
the number of children that are actually being cloned.
