Log:<br>
[AST] Cleanup ExprIterator.<br>
<br>
- Make it a proper random access iterator with a little help from iterator_adaptor_base<br>
- Clean up users of magic dereferencing. The iterator should behave like an Expr **.<br>
- Make it an implementation detail of Stmt. This allows inlining of the assertions.<br>
