Avoid computing many redundant copies of flow-step for dicts and sequences.
For example, the path-injection query has 114 different
SequenceKindorDictKind. Most of these are unused, so we don't want to compute flow-steps for them.Reduces the size of
TaintKind.getTaintForFlowStep(...), which could exceed 1Gb, to about 2% of its original size.
