gvn: bail out unavoidable non-ssa locals in repeat Fixes #141251. We cannot transform `*elem` to `array[idx1]` in the following code, as `idx1` has already been modified. ```rust mir! { let array; let elem; { array = [*val; 5]; elem = &array[idx1]; idx1 = idx2; RET = *elem; Return() } } ``` Perhaps I could transform it to `array[0]`, but I prefer the conservative approach. r? mir-opt
