Jon Ross-Perkins b42612bcec Change tuple/paren expr parsing to use placeholders. (#3849)
I've been thinking about this since we decided to add placeholders in
the parse tree. This allows a clearer division of work in check
handling, where we were doing work for ExprOpenParen that's only
necessary for tuples (splitting/renaming handle_paren.cpp accordingly).
