Add `Math.log1p` and `Math.expm1`
This commit adds two new methods to the `Math` module:
* `Math.log1p(x)`: Computes `Math.log(x + 1)`
* `Math.expm1(x)`: Computes `Math.exp(x) - 1`
These methods are often more accurate than the straightforward
computation, especially when `x` is close to zero.
The corresponding functions, `log1p` and `expm1`, are defined in the C99
standard math library.
