multiElement notation does not work for comments

[caitp]

Based on #8721 (comment) --- there may be use cases for doing something like

<!-- directive: ng-if-start someCondition -->
  <div ng-if="someCondition.someOtherCondition1">
    <img src="fancycontent.jpeg">
  </div>
  <div ng-if="someCondition.someOtherCondition2">
    <img src="otherfancycontent.jpeg">
  </div>
<!-- directive: ng-if-end -->

--- Such that the wrapper directives aren't actually included in the DOM.

It would be a bit of a refactoring of the compiler, and usually you'd be crazy to use comment directives, but it doesn't seem totally unreasonable to me.

Thoughts? Feelings?

Talked about it with Igor, as expected it's not something we're going to fix (although it should be a pretty tiny refactoring)

Related to #3379, my first angular PR :')

Yeah I guess so, looks like you got the same answer from Igor back then :p
