Fix drop handling for `if let` expressions MIR lowering for `if let` expressions is now more complicated now that `if let` exists in HIR. This PR adds a scope for the variables bound in an `if let` expression and then uses an approach similar to how we handle loops to ensure that we reliably drop the correct variables. 2021-09-01 21:52:17 +00:00			`// build-pass`
