[Mesa-dev] [MR] WIP: Improve TTN so it can be used by Gallium Nine

[Timur Kristóf]

Hi,

This MR is part of our ongoing work to support NIR in nine. We are 
currently testing on radeonsi, but our ultimate goal with this is to
make it possible for nine to run with iris (and eventually zink).

These patches give some polish to tgsi_to_nir (aka. TTN), so that it
can handle the TGSI input that it receives from nine. Any feedback on
this patch series is greatly welcome.

Some games we tested are already playable on radeonsi with NIR (and to
some degree on iris too, but with glitches).

Best regards,
