Rollup merge of #21925 - sfackler:allow-missing-copy, r=alexcrichton

 This was particularly helpful in the time just after OIBIT's
implementation to make sure things that were supposed to be Copy
continued to be, but it's now creates a lot of noise for types that
intentionally don't want to be Copy.
