as discussed in #54135

this appears to work at least on bare functions and statics. no_mangle
on impl methods doesn't work (yet?). See example below:

struct Foo;

impl Foo {
    // this is NOT external
    #[no_mangle]
    fn foo(&self) {}

    // this is NOT external
    #[no_mangle]
    pub fn bar(&self) {}
}

pub struct Bar;

impl Bar {
    // this IS external
    pub fn baz(&self) {}
}

After this change a few lints are no longer correct and would need to be
tweaked. e.g. #[no_mangle] fn foo() {} is not dead code and doesn't need to be
pub but the compiler raises two warnings about that.

Thanks for this! I was actually starting a patch for this as well locally but kept not getting a chance to go back and keep testing it. I think though it's best to fix this by not touching privacy and only touching reachability, as that's basically what's happening here (this isn't messing with privacy, only reachability).

I was planning on taking today to work on this, so I don't mind taking this over if you'd prefer!

Please go ahead. This PR was me procrastinating on some writing I have to do, but it's best if I go back to writing. 😅
