Rollup merge of #42196 - tommyip:explain_closure_err, r=nikomatsakis
Explain why a closure is `FnOnce` in closure errors. Issue: #42065 @nikomatsakis Am I going the right direction with this? ~~I am stuck in a few bits:~~ ~~1. How to trace the code to get the upvar instead of the original variable's span?~~ ~~2. How to find the node id of the upvar where the move occured?~~
