Rollup merge of #133389 - eduardosm:stabilize-const_float_methods, r=RalfJung
Stabilize `const_float_methods` Tracking issue: https://github.com/rust-lang/rust/issues/130843 Relnotes: #133383 Stabilized const API: ```rust // in `core` impl f32/f64 { pub const fn recip(self) -> Self; pub const fn to_degrees(self) -> Self; pub const fn to_radians(self) -> Self; pub const fn max(self, other: Self) -> Self; pub const fn min(self, other: Self) -> Self; pub const fn clamp(self, min: Self, max: Self) -> Self; pub const fn abs(self) -> Self; pub const fn signum(self) -> Self; pub const fn copysign(self, sign: Self) -> Self; } ``` Closes https://github.com/rust-lang/rust/issues/130843 r? libs-api cc `@RalfJung` -- I think the way const-stability attributes work have change a bit since the last time a wrote a const-stabilization PR, please make sure I got them right.
