346adf7f55 * replace explicit (sometimes incomplete) tests with calls to doshortbooleval() 
* the c-style boolean evaluation of "and" is independent of short-circuit evaluation
    (you always have to consider the complete values in case the first one is <> 0)

91e550edb6 Remove assigned but unused local variable i64 in taddnode.pass_typecheck_internal as suggested by Ondrej Pokorny
