This CL changes the way that the resolver traverses expressions to avoid stack overflows for deeply nested expressions.
Instead of having the expression resolver methods call back into
Expression(), add a TraverseExpressions() method that collects all the
expression nodes with a simple DFS.
This currently only changes the way that Expressions are traversed. We
may need to do the same for statements.
