Rollup merge of #73449 - ehuss:duplicate-lang-item, r=matthewjasper
Provide more information on duplicate lang item error. This gives some notes on the location of the files where the lang items were loaded from. Some duplicate lang item errors can be a little confusing, and this might help in diagnosing what has happened. Here's an example when hitting a bug with Cargo's build-std: ``` error: duplicate lang item in crate `core` (which `rustc_std_workspace_core` depends on): `try`. | = note: the lang item is first defined in crate `core` (which `z10` depends on) = note: first definition in `core` loaded from /Users/eric/Proj/rust/cargo/scratch/z10/target/target/debug/deps/libcore-a764da499c7385f4.rmeta = note: second definition in `core` loaded from /Users/eric/Proj/rust/cargo/scratch/z10/target/target/debug/deps/libcore-5b082675aea34986.rmeta ```
