Joe Groff 53221db84c AST: Add 'VarPattern' node. ...

We decided to go with 'var' as a distributive pattern introducer which applies to bare identifiers within the subpattern. For example, 'var (a, b)' and '(var a, var b)' would be equivalent patterns. To model this, give 'var' its own AST node with a subpattern and remove the introducer loc from NamedPattern.
