Clean up ActionView some:

  * Call _evaluate_assigns_and_ivars at the two entry points so we don't have to
    do a check at every render.
  * Make template.render viable without having to go through a wrapper method
  * Remove old TemplateHandler#render(template, local_assigns) path so we don't have
    to set self.template every time we render a template.
  * Move Template rescuing code to Template#render so it gets caught every time.
  * Pull in some tests from Pratik that test render @object in ActionView
