Detailed Description

This class can be used to assign names to VPValues.

For VPValues without underlying value, assign consecutive numbers and use those as names (wrapped in vp<>). Otherwise, use the name from the underlying value (wrapped in ir<>), appending a .V version number if there are multiple uses of the same name. Allows querying names for VPValues for printing, similar to the ModuleSlotTracker for IR values.
