Don't ICE on item in `.await` expression The code for lowering a `.await` expression missed that item IDs may already have been assigned for items inside of an `async` block, or for closures. This change means we no longer exit early after finding a `.await` in a block that isn't `async` and instead just emit the error. This avoids an ICE generated due to item IDs not being densely generated. (The `YieldSource` of the generated `yield` expression is used to avoid errors generated about having `yield` expressions outside of generator literals.) r? @cramertjResolvesrust-lang#62009 and resolvesrust-lang#61685
