Sum type info in suggestions DB (#3422) 
A draft of simple changes to the compiler to expose sum type information. Doesn't break the stdlib & at the same time allows for dropdowns. This is still broken, for example it doesn't handle exporting/importing types, only ones defined in the same module as the signature. Still, seems like a step in the right direction – please provide feedback.

# Important Notes
I've decided to make the variant info part of the type, not the argument – it is a property of the type logically.

Also, I've pushed it as far as I'm comfortable – i.e. to the `SuggestionHandler` – I have no idea if this is enough to show in IDE? cc @4e6

Enso Runtime

The Enso runtime is responsible for the actual execution of Enso code. This means that it encompasses the following functionality:

  • Parsing: Taking Enso code as input and generating an AST that maintains a sophisticated set of information about the input.
  • Desugaring: Reducing the user-facing Enso code into a simplified language known as Core.
  • Type Inference: Inferring the types of bindings in the user's code.
  • Type Checking: Checking that the inferred and provided types for bindings match up across the codebase.
  • Optimisation: Static optimisation processes to improve the performance of the user's program.
  • Code Execution: Actually running the Enso code.
  • Introspection Hooks: Providing hooks into the running code to allow the language server to inspect information about the code as it runs.

Truffle Nodes creation convention

All Truffle nodes that are expected to be created as part of ASTs should implement a public, static build method for creating an instance. If the node is DSL generated, the build method should delegate to the autogenerated create method, so that nodes are always created with build. Such a convention allows us to easily switch node back and forth between manual and DSL generated implementations, without the need to change its clients.

The only exception are nodes that are never expected to be a part of an AST – e.g. root nodes of builtin functions, for which an asFunction method should be implemented instead.

This convention should be implemented for every node throughout this codebase – if you see one not obeying it – please fix it.
