IR optimization

[Shfty]

• Strategies to reduce the amount of IR that needs to be interpreted
• Pre-evaluate expressions comprised solely of literals
  • ex. Convert 1 / 2 into 0.5 to avoid a runtime divide
• Inlining
  • ex. Replace variable bindings with their values to reduce IO overhead
  • Mainly relevant to entrypoint; may be better to hand-optimize codegen
