0001-Allow-move-array-elements-even-in-case-when-the-area.patch

The code for array.move assumes overlapping regions. Compare output for following program:

int main() {
	int[] items = new int[10];
	for(int i = 0; i < 10; i++)
		items[i] = i + 1;
	items.move(0, 3, 2);
	items.move(5, 6, 3);
	for(int i = 0; i < 10; i++)
		stdout.printf("%d: %d\n", i + 1, items[i]);
	return 0;
}
