<!-- Beginning of software-defined metadata used to implement image atomics
and multisampled image writes. For atomics, information could be
recovered from the PBE descriptor, but it is convenient to compute on the
CPU where we have ail.
This descriptor (or a pointer to it, if the extended form is used) is stashed
in the last 8 bytes of a PBE descriptor. Ordinarily used for
acceleration buffers or linear layer stride. We forbid atomics and
multisampled writes to compressed images and linear 2D arrays, leaving this
area free.
