Well... you can do that:

	var x = 0
	while x < 10 {
		defer { x += 1 } // warning: also increment x if an exception is thrown
		continue
	}

Or maybe the C-style for loop could just be made more readable. You could replace the semicolons with words:

	for var x = 0 while x < 10 defer x += 1 {
	}

But that might be slightly misleading. "defer" would imply that this part is executed when an exception is thrown, which would be unlike a regular for loop.
