This removes 2 loops from hot codepaths and adds 1 loop to a rare codepath
(restore_sampler_states), and makes sanitize_hash() slightly worse.

Sampler states, when bound, are not unbound for draw calls that don't need
them. That's OK, because bound sampler states don't add any overhead.

This results in lower CPU overhead in most cases.

i915: Always emit W on gen3

Unlike the older gen2 hardware, gen3 performs perspective
correct interpolation even for the primary/secondary colors.
To do that it naturally needs us to emit W for the vertices.

Currently we emit W only when at least one texture coordinate
set gets emitted. This means the interpolation of color will
change depending on whether texcoords/varyings are used or not.
That's probably not what anyone would expect, so let's just
always emit W to get consistent behaviour. Trying to avoid
emitting W seems like more hassle than it's worth, especially
as bspec seems to suggest that the hardware will perform the
perspective division anyway.

This used to be broken until it was accidentally fixed it in
commit c349031c27b7 ("i915: Fix texcoord vs. varying collision
in fragment programs") by introducing a bug that made the driver
always emit W. After fixing that bug in commit c1eedb43f32f
("i915: Fix wpos_tex vs. -1 comparison") we went back to the
old behaviour and caused an apparent regression.

spirv: Work around the Doom shader bug

Doom shipped with a broken version of GLSLang which handles samplers as
function arguments in a way that isn't spec-compliant.  In particular,
it creates a temporary local sampler variable and copies the sampler
into it.  While Dave has had a hack patch out for a while that gets it
working, we've never landed it because we've been hoping that a game
update would come out with fixed shaders.  Unfortunately, no game update
appears on to be on the horizon and I've found this issue in yet another
application so I think we're stuck working around it.  Hopefully, we can
delete this code one day.

st/xvmc: deal with drivers wanting different texture formats

Previously, texture formats were being used unconditionally without
checking. However nv30 supports neither RGBX8 nor R4A4/A4R4 formats. Add
sufficient fallbacks so that the nv30 driver can have working OSD.

nvc0: fix transfer of larger rectangles with DmaCopy on gk104 and up

By treating the rectangles as 1cpp, we can run up against some internal
copy engine limits and trigger a MEM2MEM_RECT_OUT_OF_BOUNDS error check
at launch time.

This commit enables the REMAP hardware, which allows us to specify both
the component size and number of components for a transfer.  We're then
able to pass in the real width/nblocksx values and not hit the limits.

There's a couple of "supported" CPPs in the list that we can't actually
hit, but are there simply because they're possible.
