the same that is used by the system-image-upgrader script in recovery
mode ...

you *have* to do it in recovery mode, else there are plenty of
mountpoints on top of the loop device that you can not easily unmount...
(and without re-initializing the bigger loop device the kernel wont
notice the bigger partition size)

none of these tools will be available in recovery mode (you would have
to port them to bionic first to even make them available)

seriously (on your PC):

sudo apt-get install qemu-user-static
sudo qemu-debootstrap --arch armhf trusty my-devel-chroot
sudo chroot my-devel-chroot
(do whatever you want to do wrt development)

is the better approach ...
