383210096c C++: Isolate models from AST dataflow's reference/object conflation 
`DataFlowFunction` models treat references a pointers - an explicit level of indirection. The AST dataflow library generally treats references as if they were the referred-to object. This commit removes a workaround in the dataflow model for unary `operator*` on smart pointers, and makes the AST dataflow library adjust the results of querying the model so that a returned reference only gets flow that was modeled as going to the dereference of the return value.

This fixes some missing flow in IR dataflow, and recovers some (presumably) missing reverse taint flow in AST taint tracking as well.

697b2dcde8 C++: Add missing store step for single-field struct use 
We have special code to handle field flow for single-field structs, but that special case was too specific. Some `Store`s to single-field structs have no `Chi` instruction, which is the case that we handled already. However, it is possible for the `Store` to have a `Chi` instruction (e.g. for `{AllAliased}`), but still have a use of the result of the `Store` directly. We now add a `PostUpdateNode` for the result of the `Store` itself in those cases, just like we already did if the `Store` had no `Chi`.
