The `coord_offset` pass is responsible for upgrading any eligible texture loads into prefetches, but a texture prefetch's capabilities are limited and cannot handle any interpolation modes aside from `smooth`. An exception is carved out for `flat` interpolation modes, but this doesn't exclude upgrading `noperspective` texture loads and results in perspective-corrected samples being provided that can severely break applications depending on this behaviour. Fixes incorrect lighting projection on Super Mario Odyssey on Skyline Emulator. Fixes incorrect dirt texture mapping on Portal 2 trace on Turnip and Zink on Turnip. Fixes incorrect lighter shadowing on Half Life 2 trace on Turnip. Signed-off-by: Mark Collins <mark@igalia.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/19842>
