// `defer` runs on EVERY exit from the loop body's scope — fall-through,
// `break`, and `continue` alike (LIFO, including entries from nested blocks
// between the loop and the jump). Covers `for` ranges and `while`.
// Regression (issue 0108): break/continue emitted a bare branch and the
// breaking iteration's defers were silently skipped.
