Does this fix just that particular bug? I'd expect all the other diagnostic items to cause similar issues, though I guess only if particular codepaths execute... |

For other diagnostic items, worse diagnostics may be produced when bootstrapping, but this one causes ICE. Given that we are close to the next release I think we can wait for other diagnostic items... |

Fix #89775
#89479 renames a lot of diagnostic items, but it happens that the beta compiler assumes that there must be DefId with
rustc_diagnostic_item = "send_trait", causing an ICE when compiling stage 0 std or stage 1 compiler. So gate it withcfg(bootstrap).The unwrap is also removed, so that existence of the diagnostic item is not required. I ripgreped the code base and this seems the only place where
unwrapis called on the return value ofget_diagnostic_item.
