Enabling feature(effects) causes const_patterns_without_partial_eq to show up

[RalfJung]

The following code works fine without the effects feature, but triggers a warning (soon to become a hard error) when the feature is enabled:

#![feature(effects)]
#[derive(Eq, PartialEq)]
pub struct TypeThatIsPartialEq(u8);
pub const GREEN: TypeThatIsPartialEq = TypeThatIsPartialEq(4);

pub const fn is_green(x: TypeThatIsPartialEq) -> bool {
    match x { GREEN => true, _ => false }
}

i think this is a duplicate of #119398

Ah, true. Why didn't you mention on Zulip that you had filed an issue?^^ Would have saved me some work...

i created the issue as a request on the zulip thread https://rust-lang.zulipchat.com/#narrow/stream/146212-t-compiler.2Fconst-eval/topic/match.20on.20const.20triggers.20warning.20with.20effects/near/410360676

Ah, I must have forgotten about that. Sorry :)
