This adapts the sample code from the two issues into test code.

Adapt the sample code from the issues into mir-borrowck/nll test cases.

The mentoring instructions were unclear here. It seems that we want these tests to fail compilation as they both unsoundly passed AST borrowck.

@chrisvittal When you said the instructions were unclear, were you referring to the step that said that the tests should include the comment // must-compile-successfully ? (Because I would agree that was an odd thing to mention, since the two cases that @nikomatsakis listed are ones where the whole point is that they start failing to compile under #![feature(nll)])

Also I think the intention is that this PR should be closing #46557 and #38899 . I don't know if it is premature to close #47366 as well, though I guess we can always reopen it if we find other MIR issues...

That was a mistake on my part. We expect errors!

can we remove the compile-flags? They should not be necessary. feature(nll) should suffice.
