[RFC 0/9] Add precise/invariant semantics to TGSI
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
