Dart for-in loops allow `var x = [1]; for (var x in x) {}`, which is not allowed in JS. If this pattern is detected, a temporary variable is introduced so the for-in initializer expression is evaluated outside of the JS for-of loop. (This issue seems to be unique to for-in loops. For loops and other kinds of variable declarations of the form `var x = ...` are not allowed to use `x` in the initializer, even if `x` is declared in an outer scope.) Also fixes an out-of-date comment in the DDC+Analyzer backend.
