Detailed Description

An operand that constitutes an expression.  Expressions include
function calls and user-defined predicate invocations.   

We need to keep a hash table of expressions.  The table entries are of
type 'struct expr', and for each expression there is a single linked
list of occurrences.   

Expression elements in the hash table.
