Auto merge of #54782 - pnkfelix:issue-54556-semi-on-tail-diagnostic, r=nikomatsakis
NLL: temps in block tail expression diagnostic This change adds a diagnostic that explains when temporaries in a block tail expression live longer than block local variables that they borrow, and attempts to suggest turning the tail expresion into a statement (either by adding a semicolon at the end, when its result value is clearly unused, or by introducing a `let`-binding for the result value and then returning that). Fix #54556
