Refactor SOYC to reduce memory footprint.

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.
