I've no idea when sample_chan would ever be 4 here, but 4 is most
definitely wrong, array textures have it as 3 as well.
Also the cayman code though unused is obviously wrong.

This adds support to the mesa state tracker for ARB_texture_multisample.

I don't think we need to create one for TGSI at this time.
Thanks to Marek for fixes to sample number picking.

The EGLConfig attributes EGL_MIN/MAX_SWAP_INTERVAL were incorrectly set to
0 and 0. This prevented clients from setting the swap interval to a
reasonable value, like 1 or 2.
Swap interval worked correctly in Mesa 9.0. The commit below introduced

If a region is larger than the estimated aperture size, we map/unmap it
by copying with the BLT engine. Which means we can't use Y-tiling.
Fixes Piglit max-texture-size and tex3d-maxsize, which regressed in my
recent change to use Y-tiling by default on Gen6+. This was due to a
botched merge conflict resolution.
v2: Return a mask of valid tilings from intel_miptree_select_tiling.
This allows us to avoid the X-tiling fallback if Y-tiling is actually
mandatory.

gen7_blorp_emit_depth_stencil_config() is only called when
params->depth.mt is non-null. Therefore, it's not necessary to do an
"if (params->depth.mt)" test inside it. The presence of this if test
was misleading static analysis tools (and briefly, me) into thinking
that gen7_blorp_emit_depth_stencil_config() might sometimes access
uninitialized data and dereference a null pointer.

When appropriate, replace each check `hiz_mt != NULL` with either a call
to intel_miptree_slice_has_hiz() or intel_renderbuffer_has_hiz(). No
behavioral change.
This prepares for selectively enabling hiz on individual miptree slices
for Haswell.
This refactoring had several side effects.
1. To prevent new warnings about discarding the const qualifier,
I removed 'const' from some variable declarations in
intel_validate_framebuffer(). The alternative was to add const
qualifiers to multiple function signatures in the
intel_renderbuffer_has_hiz call graph. Since the dominant convention
in the Intel code is to not qualify function parameters as const,
I chose to remove rather than add const qualifiers.
2. I changed the signature of brw_emit_depth_stencil_hiz() by replacing
`struct intel_mipmap_tree *hiz_mt` with `bool hiz`. The function used
hiz_mt mostly as a boolean indicator of the presence of hiz, so the
signature change is consistent with the patch's goal.

We have several places in our pull constant handling where we make a

we were writing to the dst.xyzw, so we never register coalesced it with a
later mov from dst.x to real_dst.x.
These extra channels written would be removed if we had channel-wise DCE
in the backend, but we don't. Fix it for now by just not writing these
extra channels that won't get used.

brw_draw.c contains a trim() function which modifies the vertex count
for quads and quad strips in order to discard dangling vertices. In
principle this shouldn't be necessary, since hardware since Gen4 is
capable of discarding dangling vertices by itself. However, it's
necessary because as a hack to speed up rendering on Gen 4-5, we
sometimes convert quads to trifans and quad strips to tristrips. The
trim() function isn't necessary on Gen6 and up.
This patch documents why and when the trim() function is necessary,
and avoids calling it when it's not needed.
This will avoid creating problems when we enable hardware support for
primitive restart of quads and quad strips on Haswell.

In the mailing list discussion of "glsl/linker: fix varying packing
for non-flat integer varyings." (commit 7862bde), we concluded that
since the bug only applies to integral variables, it is safer to just
apply the bug fix to integer varyings. I forgot to make the change
before pushing the patch upstream. (Note: we aren't aware of any bugs
in commit 7862bde; it just seems wise to be on the safe side).
This patch makes the change. Assuming commit 7862bde gets
cherry-picked back to 9.1, this commit should be cherry-picked too.
NOTE: This is a candidate for the 9.1 release branch.

When a varying is consumed by transform feedback, but is not used by
the fragment shader, assign_varying_locations() sets its interpolation
type to "flat" in order to ensure that lower_packed_varyings never has
to deal with non-flat integral varyings (the GLSL spec doesn't require
integral vertex outputs to be flat if they aren't consumed by the
fragment shader).
A similar situation will arise when geometry shader support is added,
since the GLSL spec only requires integral vertex shader outputs to be
flat when they are consumed by the fragment shader. This patch
modifies the linker to handle this situation too.

To minimize the variety of type conversions that lower_packed_varyings
needs to perform, it assumes that integral varyings are always
qualified as "flat". link_varyings.cpp takes care of ensuring that
this is the case (even in the circumstances where GLSL doesn't require
it).
This patch documents the assumption with an assertion, for ease in
future debugging.

Commit dfb57e7 (glsl: Fix error checking on "flat" keyword to match
GLSL ES 3.00, GLSL 1.50) relaxed the rules for integral varyings: they
only need to be declared as "flat" if they are a fragment shader
inputs. This allowed for the possibility of a vertex shader output
being a non-flat integer, provided that it was not matched to a
fragment shader input. A non-contrived situation where this might
arise is if a vertex shader generates some integral outputs which are
consumed by tranform feedback, but not by the fragment shader.
Unfortunately, lower_packed_varyings assumes that *all* integral
varyings are flat, regardless of whether they are consumed by the
fragment shader. As a result, attempting to create a non-flat
integral vertex output of a size that required packing (i.e. a size
other than ivec4 or uvec4) would cause an assertion failure in
lower_packed_varyings.
This patch prevents the assertion failure by forcing vertex shader
outputs to be "flat" whenever they are not consumed by the fragment
shader. This should have no effect on rendering since the "flat"
keyword only affects the behaviour of fragment shader inputs.
Fixes piglit test "spec/EXT_transform_feedback/nonflat-integral".
NOTE: This is a candidate for the 9.1 release branch.
