Kenneth Graunke 8a1fd43d61 iris: Handle multiple BOs backed by the same GEM object in execbuf code
With suballocation, our batch BO list may have multiple BOs that are
suballocated from the same GEM object.  We still need to track each of
those buffers for cross-batch write tracking, cache tracking, and busy
tracking.  However, we only want to include underlying GEM objects in
the actual validation list building.  The validation list entry should
have EXEC_OBJECT_WRITE if any of the BOs are marked as writable.

We use a temporary array to map GEM handles to validation list entries
so we can quickly see if we've already emitted one and update the
EXEC_OBJECT_WRITE flag as needed.
