/**
 * At its core, the algorithm first starts from each static or dynamic entry
 * point and then assigns that entry point to all modules than can be reached
 * via static imports. We call this the *dependent entry points* of that
 * module.
 *
 * Then we group all modules with the same dependent entry points into chunks
 * as those modules will always be loaded together.
 *
 * One non-trivial optimization we can apply is that dynamic entries are
 * different from static entries in so far as when a dynamic import occurs,
 * some modules are already in memory. If some of these modules are also
 * dependencies of the dynamic entry, then it does not make sense to create a
 * separate chunk for them. Instead, the dynamic import target can load them
 * from the importing chunk.
 *
 * With regard to chunking, if B is implicitly loaded after A, then this can be
 * handled the same way as if there was a dynamic import A => B.
 *
 * Example:
 * Assume A -> B (A imports B), A => C (A dynamically imports C) and C -> B.
 * Then the initial algorithm would assign A into the A chunk, C into the C
 * chunk and B into the AC chunk, i.e. the chunk with the dependent entry
 * points A and C.
 * However we know that C can only be loaded from A, so A and its dependency B
 * must already be in memory when C is loaded. So it is enough to create only
 * two chunks A containing [AB] and C containing [C].
 *
 * So we do not assign the dynamic entry C as dependent entry point to modules
 * that are already loaded.
 *
 * In a more complex example, let us assume that we have entry points X and Y.
 * Further, let us assume
 * X -> A, X -> B, X -> C,
 * Y -> A, Y -> B,
 * A => D,
 * D -> B, D -> C
 * So without dynamic import optimization, the dependent entry points are
 * A: XY, B: DXY, C: DX, D: D, X: X, Y: Y, so we would for now create six
 * chunks.
 *
 * Now D is loaded only after A is loaded. But A is loaded if either X is
 * loaded or Y is loaded. So the modules that are already in memory when D is
 * loaded are the intersection of all modules that X depends on with all
 * modules that Y depends on, which in this case are the modules A and B.
 * We could also say they are all modules that have both X and Y as dependent
 * entry points.
 *
 * So we can remove D as dependent entry point from A and B, which means they
 * both now have only XY as dependent entry points and can be merged into the
 * same chunk.
 *
 * Now let us extend this to the most general case where we have several
 * dynamic importers for one dynamic entry point.
 *
 * In the most general form, it works like this:
 * For each dynamic entry point, we have a number of dynamic importers, which
 * are the modules importing it. Using the previous ideas, we can determine
 * the modules already in memory for each dynamic importer by looking for all
 * modules that have all the dependent entry points of the dynamic importer as
 * dependent entry points.
 * So the modules that are guaranteed to be in memory when the dynamic entry
 * point is loaded are the intersection of the modules already in memory for
 * each dynamic importer.
 *
 * Assuming that A => D and B => D and A has dependent entry points XY and B
 * has dependent entry points YZ, then the modules guaranteed to be in memory
 * are all modules that have at least XYZ as dependent entry points.
 * We call XYZ the *dynamically dependent entry points* of D.
 *
 * Now there is one last case to consider: If one of the dynamically dependent
 * entries is itself a dynamic entry, then any module is in memory that either
 * is a dependency of that dynamic entry or again has the dynamic dependent
 * entries of that dynamic entry as dependent entry points.
 *
 * A naive algorithm for this proved to be costly as it contained an O(n^3)
 * complexity with regard to dynamic entries that blew up for very large
 * projects.
 *
 * If we have an efficient way to do Set operations, an alternative approach
 * would be to instead collect already loaded modules per dynamic entry. And as
 * all chunks from the initial grouping would behave the same, we can instead
 * collect already loaded chunks for a performance improvement.
 *
 * To do that efficiently, need
 * - a Map of dynamic imports per dynamic entry, which contains all dynamic
 *   imports that can be triggered by a dynamic entry
 * - a Map of static dependencies per entry
 * - a Map of already loaded chunks per entry that we initially populate with
 *   empty Sets for static entries and Sets containing all entries for dynamic
 *   entries
 *
 * For efficient operations, we assign each entry a numerical index and
 * represent Sets of Chunks as BigInt values where each chunk corresponds to a
 * bit index. Then the last two maps can be represented as arrays of BigInt
 * values.
 *
 * Then we iterate through each dynamic entry. We set the already loaded modules
 * to the intersection of the previously already loaded modules with the union
 * of the already loaded modules of that chunk with its static dependencies.
 *
 * If the already loaded modules changed, then we use the Map of dynamic imports
 * per dynamic entry to marks all dynamic entry dependencies as "dirty" and put
 * them back into the iteration. As an additional optimization, we note for
 * each dynamic entry which dynamic dependent entries have changed and only
 * intersect those entries again on subsequent interations.
 *
 * Then we remove the dynamic entries from the list of dependent entries for
 * those chunks that are already loaded for that dynamic entry and create
 * another round of chunks.

/**
 * This function tries to get rid of small chunks by merging them with other
 * chunks.
 *
 * We can only merge chunks safely if after the merge, loading any entry point
 * in any allowed order will not trigger side effects that should not have been
 * triggered. While side effects are usually things like global function calls,
 * global variable mutations or potentially thrown errors, details do not
 * matter here, and we just discern chunks without side effects (pure chunks)
 * from other chunks.
 *
 * As a first step, we assign each pre-generated chunk with side effects a
 * label. I.e. we have side effect "A" if the non-pure chunk "A" is loaded.
 *
 * Now to determine the side effects of loading a chunk, one also has to take
 * the side effects of its dependencies into account. So if A depends on B
 * (A -> B) and both have side effects, loading A triggers effects AB.
 *
 * Now from the previous step we know that each chunk is uniquely determine by
 * the entry points that depend on it and cause it to load, which we will call
 * its dependent entry points.
 *
 * E.g. if X -> A and Y -> A, then the dependent entry points of A are XY.
 * Starting from that idea, we can determine a set of chunks—and thus a set
 * of side effects—that must have been triggered if a certain chunk has been
 * loaded. Basically, it is the intersection of all chunks loaded by the
 * dependent entry points of a given chunk. We call the corresponding side
 * effects the correlated side effects of that chunk.
 *
 * Example:
 * X -> ABC, Y -> ADE, A-> F, B -> D
 * Then taking dependencies into account, X -> ABCDF, Y -> ADEF
 * The intersection is ADF. So we know that when A is loaded, D and F must also
 * be in memory even though neither D nor A is a dependency of the other.
 * If all have side effects, we call ADF the correlated side effects of A. The
 * correlated side effects need to remain constant when merging chunks.
 *
 * In contrast, we have the dependency side effects of A, which represents
 * the side effects we trigger if we directly load A. In this example, the
 * dependency side effects are AF.
 * For entry chunks, dependency and correlated side effects are the same.
 *
 * With these concepts, merging chunks is allowed if the correlated side
 * effects of each entry do not change. Thus, we are allowed to merge two
 * chunks if
 *
 * a) the dependency side effects of each chunk are a subset of the correlated
 *    side effects of the other chunk, so no additional side effects are
 *    triggered for any entry, or
 * b) The dependent entry points of chunk A are a subset of the dependent entry
 *    points of chunk B while the dependency side effects of A are a subset of
 *    the correlated side effects of B. Because in that scenario, whenever A is
 *    loaded, B is loaded as well. But there are cases when B is loaded where A
 *    is not loaded. So if we merge the chunks, all dependency side effects of
 *    A will be added to the correlated side effects of B, and as the latter is
 *    not allowed to change, the former need to be a subset of the latter.
 *
 * Another consideration when merging small chunks into other chunks is to
 * avoid
 * that too much additional code is loaded. This is achieved when the dependent
 * entries of the small chunk are a subset of the dependent entries of the
 * other
 * chunk. Because then when the small chunk is loaded, the other chunk was
 * loaded/in memory anyway, so at most when the other chunk is loaded, the
 * additional size of the small chunk is loaded unnecessarily.
 *
 * So the algorithm performs merges in two passes:
 *
 * 1. First we try to merge small chunks A only into other chunks B if the
 *    dependent entries of A are a subset of the dependent entries of B and the
 *    dependency side effects of A are a subset of the correlated side effects
 *    of B.
 * 2. Only then for all remaining small chunks, we look for arbitrary merges
 *    following the rule (a), starting with the smallest chunks to look for
 *    possible merge targets.
