Unrolled build for rust-lang#117373

Rollup merge of rust-lang#117373 - saethlin:avoid-ice-lint, r=compiler-errors

Avoid the path trimming ICE lint in error reporting

Types or really anything in MIR should never be formatted without path trimming disabled, because its formatting often tries to construct trimmed paths. In this case, the lint turns a nice error report into an irrelevant ICE.
