Doing some sorting of functions / enums (generally speaking, I've been trying to keep these loosely lexically sorted for lack of a better ordering).
Also removes some code that seems to be dead, and a minor TODO comment fix.
- Finishes remaining "todo" parse nodes.
- Improving error recovery for invalid designators and structs, so that the parse tree still looks similar to a valid parse tree.
- Call expressions now have the thing being called as a child (of the start) instead of a sibling.
- Use of Start is replacing use of End in several parse nodes, like structs and call expressions.
- Adjusting documentation of parse node structures in an attempt to make it more consistent and understandable.
- The current state for interfaces and if/else is mostly being documented, not altered.
First change towards re-implementing interfaces using the new parser. I kept it small to make sure we are on the same page regarding stack states and how the parse tree should look like.
