Running Tomb Raider on Nouveau I found some flicker caused by ignoring precise modifiers on variables inside Nouveau. This series add precise/invariant handling to TGSI, which can be then used by drivers to disable certain unsafe optimisations which may otherwise alter calculations, which depend on having the same result across shaders. This series fixes this bug in Tomb Raider and one CTS test
