This class is part of the public API, and contains the functionality that's common to ForElement and ForStatement. Adding this class allows us to change the type of `ForLoopParts.parent` from `AstNode?` to `ForLoop`. I intend to make use of this in a follow-up CL that makes improvements to the "remove dead code" fix, as part of my work on sound flow analysis.
