Avoid using assert in Scala, use assertInJvm to elide it in production (#11027) 
Fixes #11022 and in general fixes #5787 by avoiding calls to Scala's `assert` function and using regular one written in Java that uses `assert` keyword and is thus sensitive to `-ea` command line option of the JVM. Use `assertInJvm` in newly written Scala code to get typical JVM behavior on `assert`.

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.
