//! Tests that with `-Zinline-mir`, we do NOT get an error that points to the
//! implementation of `UnsafeCell` since that is not actionable by the user:
//!
//! ```text
//! error: moving 9999 bytes
//!   --> /rustc/FAKE_PREFIX/library/core/src/cell.rs:2054:9
//!    |
//!    = note: value moved from here
//! ```
//!
//! We want the diagnostics to point to the relevant user code.
