bors d5b40bf469 Auto merge of #78343 - camelid:macros-qualify-panic, r=m-ou-se
Qualify `panic!` as `core::panic!` in non-built-in `core` macros

Fixes #78333.

-----

Otherwise code like this

    #![no_implicit_prelude]

    fn main() {
        ::std::todo!();
        ::std::unimplemented!();
    }

will fail to compile, which is unfortunate and presumably unintended.

This changes many invocations of `panic!` in a `macro_rules!` definition
to invocations of `$crate::panic!`, which makes the invocations hygienic.

Note that this does not make the built-in macro `assert!` hygienic.
