Reviewers: cromwellian, Description: Before: correlations from parents get copied to every single child SourceInfoCorrelation, using lots of extra memory.
After: SourceInfoCorrelations have parent pointers, and the list of correlations is computed on demand, saving a lot of memory. Other changes: - Got rid of the idea of merging and having more than one correlation of a given type per node. These features were only used in practice a couple of minor cases (static evaluation of string concats, for example). - Generally, not routing through JProgram to create child nodes. - Cleaned up a couple of wrongful/wonky attributes. - Output is nearly identical after this change.
