change how we report `err_out_of_scope` borrowck errors Also, remove the explicit code detecting borrows over a yield. It turns out not to be necessary -- any such borrow winds up with a lifetime that is part of the generator type, and therefore which will outlive the generator expression itself, which yields an `err_out_of_scope`. So instead we intercept those errors and display them in a nicer way. 2017-07-15 06:52:49 -04:00			error[E0501]: cannot borrow `x` as immutable because previous closure requires unique access
