-/**
- * Optimiser component that modifies an AST in place, turning complex
- * expressions into simple expressions and multiple variable declarations.
- *
- * Code of the form
- *
- * sstore(mul(x, 4), mload(y))
- *
- * is transformed into
- *
- * let a1 := mload(y)
- * let a2 := mul(x, 4)
- * sstore(a2, a1)
- *
- * The transformation is not applied to loop conditions, because the loop control flow
- * does not allow "outlining" the inner expressions in all cases.
- *
- * The final program should be in a form such that with the exception of a loop condition,
- * function calls can only appear in the right-hand side of a variable declaration,
- * assignments or expression statements and all arguments have to be constants or variables.
