fix evaluation of a function or array symbol in conditionals
Functions and arrays degenerate as pointers in most context
but this wasn't done in the case of conditionals.
As a result the value of the conditional after linearization
was invalid.
Fix this by calling degenerate() in evaluate_conditional().
