[Mesa-dev] [PATCH v6 00/34] Nouveau NIR support

[Karol Herbst]

I mainly cleaned the series and implemented missing features or fixed stuff:
* converted to C style comments
* added nv50 support
* added interpolateAt
* fixed Arrays of Images
* fixed Images on pre Maxwell GPUs
* disable MS Images when using NIR

Piglit pass rates are pretty good. With Fermi/Kepler1 some spilling bugs are
hit. And with nv50 there are minor issues with gl_PointCoord. But because NIR
support is hidden behind an envvar I think it is fine to fix that up in follow
ups.

On Nouveau we support tg4 with for constant offsets as well, but this I want
to mainline in a seperated series, because it requires changes to NIR itself.

Support for bindless textures are missing, because it isn't support in NIR yet
same goes for MS Images.
