This primarily tests that:
- multiple GPUs with the same GPU modifier parameters result
in the same tiling layout.
- The size & alignment calculations don't change for a given
modifier & image parameters.
It does this primarily based on addrlib. Radeonsi has used addrlib
for the retiling of displayable DCC for a while already, so the
DCC tiling should be pretty reliable.
