Looking up known-key names
Getting the Uniques of Names

Description

This is where we define a mapping from Uniques to their associated known-key Names for things associated with tuples and sums. We use this mapping while deserializing known-key Names in interface file symbol tables, which are encoded as their Unique. See Note [Symbol table representation of names] for details.
