Auto merge of #52011 - oli-obk:dont_you_hate_it_too_when_everything_panics_constantly, r=eddyb
Allow panicking with string literal messages inside constants
r? @eddyb
cc https://github.com/rust-lang/rust/issues/51999
we can't implement things like `panic!("foo: {}", x)` right now because we can't call trait methods (most notably `Display::fmt`) inside constants. Also most of these impls probably have loops and conditions, so it's messy anyway.
But hey `panic!("foo")` works at least.
cc @japaric got any test ideas for `#![no_std]`?
