This translates the GLSL compiler's IR into vec4_instruction IR,
generating code to load coordinates, LOD info, shadow comparitors, and
so on into the appropriate message registers.
It turns out that the SIMD4x2 parameters are identical on Gen 5-7, and
the Gen4 code is similar enough that, unlike in the FS, it's easy enough
to support all generations in a single function.
v2: Load zeros for missing coordinates (fixing vs-texelFetch-sampler1D
and 2D on G45), and fix G45 message length for shadow comparisons.

Prior to Ironlake, cube maps were stored as 3D textures. In recent
refactoring, we removed a separate "layers" parameter in favor of using
depth. Unfortunately, depth was getting minified, which is only correct
for actual 3D textures.
Fixes piglit tests:
- bugs/crash-cubemap-order
- fbo/fbo-cubemap
- texturing/cubemap
Also changes texturing/cubemap npot from abort to fail.

All of the extensions require that both libGL and either the server or

advertised. It seems safe to assume that none of the other components
on OS X will enable these extensions, so all the #ifdef blocks here
just clutter the code.

__glXInitialize calls AllocAndFetchScreenConfigs.
AllocAndFetchScreenConfigs unconditionally sends a glXQuerySeverString
request to the server. This request is only supported with GLX 1.1 or

servers. How many more similar bugs lurk in the code that nobody has

Send the DestroyContext protocol immediately when glXDestroyContext is
called, and never call it when glXFreeContextEXT is called. In both
cases, either destroy the client-side structures or, if the context is
current, set xid to None so that the client-side structures will be
destroyed later.
I believe this restores the behavior of the original SGI code. See
src/glx/x11 around commit 5df82c8. The spec doesn't say anything
about glXDestroyContext not really destroying imported contexts (it
acts like glXFreeContextEXT instead), but that's what the original
code did. Note that glXFreeContextEXT on a non-imported context does
not destroy it either.
Fixes the piglit test glx-free-context.

Each of the DRI, DRI2, and DRISW backends contain code like the
following in their create-context routine:
if (shareList) {
pcp_shared = (struct dri2_context *) shareList;
shared = pcp_shared->driContext;
}
This assumes that the glx_context *shareList is actually the correct
derived type. However, if shareList was created as an
indirect-rendering context, it will not be the expected type. As a
result, shared will contain garbage. This garbage will be passed to
the driver, and the driver will probably segfault. This can be
observed with the following GLX code:
ctx0 = glXCreateContext(dpy, visinfo, NULL, False);
ctx1 = glXCreateContext(dpy, visinfo, ctx0, True);
Create-context is the only case where this occurs. All other cases
where a context is passed to the backend, it is the 'this' pointer
(i.e., we got to the backend by call something from ctx->vtable).
To work around this, check that the shareList->vtable->destroy method
is the same as the destroy method of the expected type. We could also
check that shareList->vtable matches the vtable or by adding a "tag"
to glx_context to identify the derived type.

where there weren't any before.
