script engine: switch() fixup and optimizations

- optimize/transform switch() statements into:
   - jump tables (if small enough)
   - condition tables
   - simple blocks (optimization when the expression in switch()
     is constant)
   - only a condition evaluator (when the switch body is empty,
     but the switch expression has side-effect and hence cannot be
     optimized away)
