add support for unchecked math add compiler support for ```rust /// Returns the result of an unchecked addition, resulting in /// undefined behavior when `x + y > T::max_value()` or `x + y < T::min_value()`. pub fn unchecked_add<T>(x: T, y: T) -> T; /// Returns the result of an unchecked substraction, resulting in /// undefined behavior when `x - y > T::max_value()` or `x - y < T::min_value()`. pub fn unchecked_sub<T>(x: T, y: T) -> T; /// Returns the result of an unchecked multiplication, resulting in /// undefined behavior when `x * y > T::max_value()` or `x * y < T::min_value()`. pub fn unchecked_mul<T>(x: T, y: T) -> T; ``` cc https://github.com/rust-lang/rfcs/issues/2508
