BoundedSegmentedDataContainer.removeSegments is slow

BoundedSegmentedDataContainer.removeSegments iterates over the evictionCache entries (through the entries map) and computes the segment for each entry, then deletes the entry if its segment is one of the removed segments. Computing the segment of many entries can be expensive, so it would be better to remove the entries from evictionCache by iterating over the already-segmented maps (before removing them).
