Simplify loop conditions so that they won't generate statements Introduce an AST traverser that can move the evaluation of certain types of loop conditions and loop expressions inside the loop. This way subsequent AST transformations don't have to worry about cases where they have to insert new statements to implement a loop condition or expression. This includes the revert of "Unfold short-circuiting operators in loop conditions correctly". The new traverser covers the loop cases that used to be handled in UnfoldShortCircuitToIf.
