[#4287] Fix the undefined evaluate_match error when comparing functions

Ticket #4238 introduced a problem that a function couldn't compare to
another value until after it was evaluated, and AST::Function didn't have the
evaluate_match method.  This change moves that method from AST::Leaf to AST.

The special casing necessary for doing comparisons between AST objects
feels messy and could probably be encapsulated better.  I've created
ticket #4291 to remind us to refactor this at some point.
