Previously the renderers were fixed so that they inserted extra "adjacent" statements after the last static property of classes. In order to help the build-optimizer (in Angular CLI) to be able to tree-shake classes effectively, these statements should also appear after any helper calls, such as `__decorate()`. This commit moves the computation of this positioning into the `NgccReflectionHost` via the `getEndOfClass()` method, which returns the last statement that is related to the class.
