rollup merge of #23953: dhuseby/master

@alexcrichton here are the two most recent Bitrig snapshots.  As usual, please upload the snapshots to the snapshot server:

BTW, I was just able to get the Bitrig Rust build to pass "make check" so I'll submit a PR once this lands to fix the tests and get the Bitrig buildbot to finally complete a build.  That will hopefully end this nonsense of hand building and uploading snapshots. 👍
