"requires owned_box lang_item" causes panic

[unizippro]

Code

Unfortunatly i was unable to find the specific code causing the crash. But i have verified the linting runs with clippy 0.1.52 (88f19c6 2021-05-03).

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust-clippy/issues/new

note: Clippy version: clippy 0.1.53 (53cb7b0 2021-06-17)

query stack during panic:
#0 [analysis] running analysis passes on this crate
end of query stack

[flip1995]

Reproducer:

#![feature(lang_items, start, libc)]
#![no_std]

use core::panic::PanicInfo;

struct S;

impl Drop for S {
    fn drop(&mut self) {}
}

#[start]
fn main(argc: isize, argv: *const *const u8) -> isize {
    if let Some(_) = Some(S) {
    } else {
    }
    0
}

#[panic_handler]
fn panic(_info: &PanicInfo) -> ! {
    loop {}
}

#[lang = "eh_personality"]
extern "C" fn eh_personality() {}

I think I have a fix for this ICE.
