error: aborting due to previous error
rework how we handle the type of loops First, we keep a `CoerceMany` now to find the LUB of all the break expressions. Second, this `CoerceMany` is actually an `Option<CoerceMany>`, and we store `None` for loops where "break with an expression" is disallowed. This avoids silly duplicate errors about a type mismatch, since the loops pass already reports an error that the break cannot have an expression. Finally, since we now detect an invalid break target during HIR lowering, refactor `find_loop` to be infallible. Adjust tests as needed: - some spans from breaks are slightly different - break up a single loop into multiple since `CoerceMany` silences redundant and derived errors - add a ui test that we only give on error for loop-break-value 2017-03-17 10:49:53 -05:00			error[E0571]: `break` with value from a `for` loop
