When intel_finalize_mipmap_tree() calls intel_miptree_copy_teximage()
to reassemble a depth miptree that has been broken apart into pieces
(to deal with misalignment of levels/layers within the miptree), it
just copies the depth data, not the HiZ data. This is reasonable,
since the alignment restrictions of HiZ are a large part of the reason
why the miptree had to be broken apart in the first place. However,
in order for the depth copy to be sufficient, we need to do a depth
resolve first, to make sure any deferred depth writes that are in the
HiZ buffer get performed.

The commit below exposed a bug in dri2_add_config.
commit 3998f8c6b5
Author: Ralf Jung <post@ralfj.de>
Date: Tue Apr 9 14:09:50 2013 +0200
egl/x11: Fix initialisation of swap_interval
This little code snippet near the bottom of dri2_add_config,
if (double_buffer) {
...
conf->base.MinSwapInterval = dri2_dpy->min_swap_interval;
conf->base.MaxSwapInterval = dri2_dpy->max_swap_interval;
}
it never did what it claimed to do. The assignment never changed the value
of conf->base.MaxSwapInterval, because dri2_dpy->max_swap_interval was,
until the above exposing commit, unitialized here. That is,
conf->base.MaxSwapInterval was 0 before and after assignment. Ditto for
the min swap interval.
Above the troublesome code snippet, the call to _eglFilterArray rejects
the config as unmatching if its swap interval bounds differ from the base
config's. Before the exposing commit, at the call to _eglFilterArray, the
swap interval bounds were always [0,0], and hence no config was rejected
due to swap interval.
After the exposing commit, _eglFilterArray incorrectly rejected some
configs, which prevented dri2_egl_config::dri_double_config from getting
set for the rejected config, which resulted in a NULL pointer getting
passed into dri2CreateNewDrawable, and then segfault.
The solution: set the swap interval bounds before _eglFilterArray.

(cherry picked from commit b5b6460c40)
According to the Ivybridge PRM, Volume 4 Part 1, page 130, in the
section for the sample_d message: "The r coordinate contains the faceid,
and the r gradients are ignored by hardware."
This doesn't match GLSL, which provides gradients for all of the
coordinates. So we would need to do some math to compute the face ID
before using sample_d. We currently don't have any code to do that.
However, we do have a lowering pass that converts textureGrad to
textureLod, which solves this problem. Since textureGrad on three
components is sufficiently obscure, it's not a performance path.
For now, only handle samplerCubeShadow; we need tests for samplerCube
and samplerCubeArray.

(cherry picked from commit e2f887b243)
Consider the following shader:
vec4 f(vec4 v) { return v; }
vec4 f(vec4 v);
The prototype exactly matches the signature of the earlier definition,
so there's absolutely no point in it. However, it doesn't appear to
be illegal. The GLSL 4.30 specification offers two relevant quotes:
"If a function name is declared twice with the same parameter types,
then the return types and all qualifiers must also match, and it is the
same function being declared."
"User-defined functions can have multiple declarations, but only one
definition."
In this case the same function was declared twice, and there's only one
definition, which fits both pieces of text. There doesn't appear to be
any text saying late prototypes are illegal, so presumably it's valid.
Unfortunately, it currently triggers an assertion failure:
ir_dereference_variable @ <p1> specifies undeclared variable `v' @ <p2>
When we process the second line, we look for an existing exact match so
we can enforce the one-definition rule. We then leave sig set to that
existing function, and hit sig->replace_parameters(&hir_parameters),
unfortunately nuking our existing definition's parameters (which have
actual dereferences) with the prototype's bogus unused parameters.
Simply bailing out and ignoring such late prototypes is the safest
thing to do.

Running piglit with this was causing all sort of weird stuff happening
to my desktop (Chromium webpages become blank, Qt Creator flickered,
etc). I tracked this down to shared memory segment leakage when GL is
not shutdown properly. The segments can be seen running `ipcs` and
looking for nattch==0.
This changes fixes this by calling shmctl(IPC_RMID) soon after creation
(which does not remove the segment immediately, but simply marks it for
removal when no more processes are attached).
This matches src/mesa/drivers/x11/xm_buffer.c behaviour.

- move shmctl(IPC_RMID) after XShmAttach() for *BSD, per Chris Wilson
- remove stray debug printfs, spotted by Ian Romanick

Inserting the value for the second quad in the wrong place for the
following shuffle. This meant the row or image stride was undefined which is
quite catastrophic, can lead to bogus texels fetched or just segfault.
This code is only hit for SoA path currently, still surprising it
didn't crash more or caused more visible issues (I think llvm used a
broadcast shuffle for the undefined parts of the vector, hence the undefined
value for the second quad was just the same as that from the first quad,
so as long as both quads hit the same mip level everything was fine, and since
lower mips always have the same large stride it made it less likely to
hit out-of-bound memory in case of differing lods).
