Detailed Description
This stores lookup tables to make manipulating and working with the IR more efficient.
There are two phases to this object: the "building" phase in which it is "write only" and then the "using" phase which is read-only (and thus can be used by multiple threads). The "freeze" method transitions between the two states.
