texelFetch sampler1/2DArray on nv50 gallium
...er2DArray. I nuked the logic in
nv50_ir_lowering_nv50.cpp:604 that does the f32 -> u32 conversion, and
it seems to be passing now. TBH, I have no clue how the parameters are
passed around and what that a[] is, but it seems like it's a u32 to
begin with? (Or that it's the same format that texfetch expects.)
Perhaps this differs across card revisions? It would be interesting if
someone with an original nv50, nva0, and nva3+ cards (those are the
interesting 3d-related chip revisions) could run texelFetch as well to
see whether it fails for them as well. Here's what I'm running:

[PATCH] nvc0/ir: move sample id to second source arg to fix sampler2DMS
The nvc0 texfetch instruction expects the sample id to be in the second
source (usually used for the offset) rather than as part of the texture
coordinate.
This fixes all the sampler2DMS/Array tests on nvc0.

[PATCH 00/19] nv50: add sampler2DMS/GP support to get OpenGL 3.2
OK, so there's a bunch of stuff in here. The geometry stuff is based on the
work started by Bryan Cain and Christoph Bumiller.
Patches 01-12: Add support for geometry shaders and fix related issues
Patches 13-14: Make it possible for fb clears to operate on texture attachments
with an explicit layer set (as is allowed in gl 3.2).
Patches 15-17: Make ARB_texture_multisample work
