radv: Add render loop detection in renderpass.
VK spec 7.3: "Applications must ensure that all accesses to memory that backs image subresources used as attachments in a given renderpass instance either happen-before the load operations for those attachments, or happen-after the store operations for those attachments." So the only renderloops we can have is with input attachments. Detect these. Reviewed-by: Dave Airlie <[email protected]>
