------------------------------------------------------------------------------
  The bytecode translator is responsible for converting incoming bytecode instructions into a high-level intermediate representation. This IR is of a lower level than the bytecode and breaks complex bytecode operations into several simple instructions to expose more opportunities to later high-level optimization phases. For example, loading an object field is broken up into operations that perform a null check of the object reference, load the base address of the object, compute the address of the field, and load the value at that computed address.
