Adds: - optimizer/BinaryOperatorOptimizer: optimizes expressions with a binary operator - assignments will be handled by optimizer/AssignmentOptimizer - optimizer/BinaryOperatorWithFloatOptimizer: optimizes binary operator expressions with a FloatValue left-hand side - optimizer/BinaryOperatorWithIntegerOptimizer: optimizes binary operator expressions with an IntegerValue left-hand side - optimizer/BinaryOperatorWithStringOptimizer: optimizes binary operator expressions with a StringValue left-hand side
