etnaviv: Supertiled texture support on gc3000

Support supertiled textures on hardware that has the appropriate
feature flag SUPERTILED_TEXTURE.

Most of the scaffolding was already in place in etna_layout_multiple:

   case ETNA_LAYOUT_SUPER_TILED:
      *paddingX = 64;
      *paddingY = 64;
      *halign = TEXTURE_HALIGN_SUPER_TILED;

So this is just a matter of allowing it.

freedreno: add support for hw accumulating queries

Some queries on a4xx and all queries on a5xx can do result accumulation
on CP so we don't need to track per-tile samples.  We do still need to
handle pausing/resuming while switching batches (in case the query is
active over multiple draws which are executed out of order).

So introduce new accumulated-query helpers for these sorts of queries,
since it doesn't really fit in cleanly with the original query infra-
structure.

i965/vec4: Avoid reswizzling MACH instructions in opt_register_coalesce().

opt_register_coalesce() was optimizing sequences such as:

   mul(8) acc0:D, attr18.xyyy:D, attr19.xyyy:D
   mach(8) vgrf5.xy:D, attr18.xyyy:D, attr19.xyyy:D
   mov(8) m4.zw:F, vgrf5.xxxy:F

into:

   mul(8) acc0:D, attr18.xyyy:D, attr19.xyyy:D
   mach(8) m4.zw:D, attr18.xxxy:D, attr19.xxxy:D

This doesn't work - if we're going to reswizzle MACH, we'd need to
reswizzle the MUL as well.  Here, the MUL fills the accumulator's .zw
components with attr18.yy * attr19.yy.  But the MACH instruction expects
.z to contain attr18.x * attr19.x.  Bogus results ensue.

No change in shader-db on Haswell.  Prevents regressions in Timothy's
patches to use enhanced layouts for varying packing (which rearrange
code just enough to trigger this pre-existing bug, but were fine
themselves).

mesa/vbo: move some Draw checks out of validation

These checks do not generate any errors. Move them so we can add
KHR_no_error support and still make sure we do these checks.

radv/ac: add support for indirect access of descriptor sets.

We want to expose more descriptor sets to the applications,
but currently we have a 1:1 mapping between shader descriptor
sets and 2 user sgprs, limiting us to 4 per stage. This commit
check if we don't have enough user sgprs for the number of
bound sets for this shader, we can ask for them to be indirected.

Two sgprs are then used to point to a buffer or 64-bit pointers
to the number of allocated descriptor sets. All shaders point
to the same buffer.

We can use some user sgprs to inline one or two descriptor sets
in future, but until we have a workload that needs this I don't
 think we should spend too much time on it.
