StatementSearchVisitor<T> mixin

A StatementVisitor whose visit* methods default to returning null, but which returns the first non-null value returned by any method.

This can be extended to find the first instance of particular nodes in the AST.

This supports the same additional methods as RecursiveStatementVisitor.
