The GPU apparently goes looking for constants even though there are no
shader stages enabled, and gets stuck because we haven't told it there are
no constants to collect. If any other user of the 3D pipeline had run
(even the Render accel of the X server!) since power on, then the in-GPU
constant buffers would have been set up with some contents we didn't use,
and we would succeed.

NOTE: This is a candidate for the stable branches.
We are already emitting a EVENT_TYPE_CACHE_FLUSH_AND_INV_EVENT packet
when this flush flag is set, so flushing the dest caches with a
SURFACE_SYNC should not be necessary.
The motivation for this change is that emitting a SURFACE_SYNC packet with
the CB bits set was causing compute shaders to hang on Cayman.

Remove all the glDraw* functions from the GLvertexformat structure.
The point of that dispatch struct is to handle all the functions which
dispatch differently depending on whether we're inside glBegin/End.
glDraw* are never allowed inside glBegin/End so we can remove those
entries.
This simplifies the code paths and gets rid of quite a bit of code.

If the currently compiled primitive state is PRIM_UNKNOWN we should
not return true from _mesa_inside_dlist_begin_end(). This lets us
simplify the calls to that function.
Note, the call to _mesa_inside_dlist_begin_end() in vbo_save_EndList()
should have probably been checking for PRIM_UNKNOWN too, but it wasn't.
So there's no code change change.

The old code didn't make sense. The clause in question did the

a glBegin/End pair and we're starting a new primitive, that's an
error.

The _save_OBE_DrawArrays/Elements/RangeElements() functions are
called when building a display list and we know we're outside
glBegin/End.
We shouldn't call the normal _mesa_validate_DrawArrays/Elements()
functions here because those functions only work properly in immediate
mode or during dlist execution. At dlist compile time, we can't call
_mesa_update_state(), etc. and examine the current state since it won't
apply when the list is executed later.

This removes the test for _mesa_inside_dlist_begin_end().
If ctx->Driver.CurrentSavePrimitive==PRIM_UNKNOWN (the initial value),
_mesa_inside_dlist_begin_end() will, confusingly, return TRUE.
So we didn't set the ctx->ListState.Current.ShadeModel value and it
remained in its indeterminate state.
This didn't effect correctness, but it defeated the intended optimization
of dropping redundant glShadeModel() state changes in order to
coalesce sequences of drawing commands.
Verified with new piglit gl-1.0-dlist-shademodel test.

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.
