Since [1], `compiler-builtins` makes a certain set of math symbols weakly available on all platforms. This means we can begin exposing some of the related functions in `core`, so begin this process here. It is not possible to provide inherent methods in both `core` and `std` while giving them different stability gates, so standalone functions are added instead. This provides a way to experiment with the functionality while unstable; once it is time to stabilize, they can be converted to inherent. For `f16` and `f128`, everything is unstable so we can move the inherent methods. The following are included to start: * floor * ceil * round * round_ties_even * trunc * fract * mul_add * div_euclid * rem_euclid * powi * sqrt * abs_sub * cbrt These mirror the set of functions that we have in `compiler-builtins` since [1].
