Turns out that my recent elimination of the 'redundant' flatten_andors()
code in prepqual.c had a small drawback: the flatten_andors code was
able to cope with deeply nested AND/OR structures (like 10000 ORs in
a row), whereas eval_const_expressions tends to recurse until it
overruns the stack.  Revise eval_const_expressions so that it doesn't
choke on deeply nested ANDs or ORs.
