The main problem was that the loop body was treated as an expression that was one of the peer result values of a loop, when in reality the loop body is noreturn and only the `break` operands are the result values of loops. This was solved by introducing an override that prevents rvalue() from emitting a store to result location instruction for loop bodies. An orthogonal change also included in this commit is switching `elem_val` index expressions to using `coerced_ty` and doing the coercion to `usize` inside `Sema`, resulting in smaller ZIR (since the cast becomes implied). I also changed the break operand expression to use `reachableExpr`, introducing a new compile error for double break. This makes a few more behavior tests pass for `while` and `for` loops. |
