405babf5af Reflected XSS query: exclude more uses of encoding/json.Marshal 
Previously we only detected these if the marshalling directly fed the request body within the same function; now it's a general sanitiser for the purposes of XSS.

5068b8b195 Add PostUpdateNodes for nested structs and arrays 
This creates a PostUpdateNode for x in the contexts `x.field[element]`, `x.field.otherfield`, `x[element].field` and so on.

Most uses of PostUpdateNode implicitly assume its old definition, but our protobuf model benefits.

fb85ccb2a5 Look through implicit deref operations when propagating taint down a chain of field- and element-access instructions. 
This enables us to use PostUpdateNode properly. Also introduce a test showing a case where this doesn't work, because the underlying variable doesn't have a post-update node.
