Auto merge of #54355 - pnkfelix:issue-22323-regression-test, r=davidtwco
NLL: regression test for "dropck: track order of destruction for r-value temporaries"
Once this lands, we can remove the E-needstest from #22323.
(We shouldn't close the bug itself, however, because we are leaving the NLL-fixed-by-NLL bugs open until NLL is turned on by default.)
