…te-must-look-at-parents-of-closures, r=davidtwco borrowck=migrate must look at parents of closures This fixes the NLL migration mode (which is the default with edition=2018) to inspect all parents of a closure in addition to the closure itself when looking to see if AST-borrowck issues an error for the given code. This should be a candidate for beta backport. Fix rust-lang#55492
