- Use a bitset rather than a HashSet for the live-set fixpoint computation; - Use a dense index space consisting *only* of block-crossing values for those bitsets, to keep them smaller; - Use a local dense liveset datastructure that uses epoch-numbers-per-slot to allow O(1) clearing between blocks. Overall, speeds up compilation on a very large input from ~173 seconds to ~7 seconds.
