commit 6a8ff3b550ec29ec5a6c5c61a2053c2bd0627166
Author: Lionel Landwerlin <lionel.g.landwerlin@intel.com>
Date:   Thu Oct 19 15:49:51 2023 +0300

    intel/compiler: store u_printf_info in prog_data
    
    So that the driver can decode the printf buffer.
    
    We're not going to use the NIR data directly from the driver
    (Iris/Anv) because the late compile steps might want to add more
    printfs.
