I got this output with an ICE:

error: internal compiler error: compiler/rustc_middle/src/ty/query.rs:440:1: `tcx.item_attrs(DefId(0:3 ~ mycrate_impl[f883]::{use#1}))` is not supported for local crate;
                                
                                                        hint: Queries can be either made to the local crate, or the external crate. This error means you tried to use it for one that's not supported.
                                
                                                        If that's not the case, item_attrs was likely never assigned to a provider function.

Very weird left padding.

Wrap missing provider message correctly

Fixes rust-lang#108429

```
error: internal compiler error: compiler/rustc_middle/src/ty/query.rs:441:1: `tcx.trigger_delay_span_bug(DefId(0:3 ~ test[78c5]::main))` is not supported for local crate;
                                hint: Queries can be either made to the local crate, or the external crate. This error means you tried to use it for one that's not supported.
                                If that's not the case, trigger_delay_span_bug was likely never assigned to a provider function.
