## Message

```
Merge branch 'std.math.atan: Add @Vector(?,f32) and @Vector(?,f64) support'

Add SIMD support for atan (f32 and f64), based on the [ARM
impl](https://github.com/ARM-software/optimized-routines/blob/master/math/aarch64/advsimd/atanf.c).
To reduce branching, more polynomial approximation is used.
