Stabilize ControlFlow::{is_break, is_continue}

[ecstatic-morse]

The type itself was stabilized in 1.55, but using it is not ergonomic without these helper functions. Stabilize them.

Random extremely minor comment: control_flow_enum_is feels a bit weird to read as a feature name. I'm expecting to find something else after the "is". I understand the reasoning, and at the end of the day it's not like users are going to need to turn on a stabilized feature, but it still seems a bit suboptimal.

@rust-lang/libs-api:
@rfcbot fcp merge

impl<B, C> ControlFlow<B, C> {
    pub fn is_break(&self) -> bool;
    pub fn is_continue(&self) -> bool;
}

The ControlFlow type has been stable since #85608:

pub enum ControlFlow<B, C = ()> {
    Continue(C),
    Break(B),
}
