## A DW_TAG_GNU_template_parameter_pack with three identical
## DW_TAG_template_type_parameter children (all referring to the same
## int base type) must be preserved as three separate child DIEs after
## linking. Before the parallel linker registered the pack tag with
## SyntheticTypeNameBuilder, pack children received no ordered synthetic
## key and TypePool deduplicated the three siblings down to one.
