Use new region infer errors for explaining borrows This gives at least some explanation for why a borrow is expected to last for a certain free region. Also: * Reports E0373: "closure may outlive the current function" with NLL. * Special cases the case of returning a reference to (or value referencing) a local variable or temporary (E0515). * Special case assigning a reference to a local variable in a closure to a captured variable. 2018-10-14 09:12:02 -05:00			`let ref mut x = 1234543;`
