Subject: Starting to add intermediate representation (IR)

Right now none of this is hooked up, but I want to get things checked in incrementally rather than have along long-lived branches.

- Added placeholder declarations for IR representation of instructions, basic blocks, etc.

- Start adding a `lower-to-ir` pass to translate from AST representation to IR

Again: none of this is functional, so it shouldn't mess with existing users of the compiler.
