Some changes are needed to build on debian because of the switch of the guest OS to bionic.

lxc that comes with debian is not high enough version to support bionic (the minimum is 2.1.1), so need to build from scratch.

debootstrap that comes with debian will give the following error:

    $ bin/make-base-vm --lxc --suite bionic --arch amd64                                                                                              
 E: No such script: /usr/share/debootstrap/scripts/bionic

Subject: [PATCH] etnaviv: NEON implementations of tiling/untiling

Experiemental NEON implementation of tiling/untiling that adds
specialized NEON function for tiling 8, 16, 32 bit per element
4x4 tiles. To optimize memory read/write sizes, there are functions that
process multiple horizontically adjactent tiles as well. These
are automatically used for the part that consists of whole tiles.
