Don't evaluate short-circuited preprocessor expressions ESSL 3.00 spec section 3.4 mentions that the second operand in a logical && or || preprocessor operation is evaluated only if the first operand doesn't short-circuit the expression. The non-evaluated part of a preprocessor expression may also have undefined identifiers. Make the expression parser follow the spec by ignoring errors that are generated inside short-circuited expressions. This includes undefined identifiers and divide by zero.
