Based from the code from the good old python state tracker.
Extremely handy to diagnose regressions in state trackers.

Not used yet but there's a couple of places in llvmpipe which should use this
(occlusion count is currently very inefficent if there's no cpu popcnt
instruction).
Handle PIPE_QUERY_GPU_FINISHED and PIPE_QUERY_TIMESTAMP_DISJOINT, and
also fill out the ps_invocations and c_primitives from the
PIPE_QUERY_PIPELINE_STATISTICS (the others in there should already
be handled). Note that ps_invocations isn't pixel exact, just 16 pixel
exact but I guess it's better than nothing.
Doesn't really seem to work correctly but there's probably bugs elsewhere.

The driver can do render_condition but wasn't handling the occlusion
and so_overflow predicates (though the latter might not work yet due
to gs support).

The semantics didn't really make sense, not really matching neither d3d9
(though the docs are all broken there) nor d3d10. So make it match d3d10
semantics, which actually gives meaning to the "disjoint" part.
Drivers are fixed up in a very primitive way, I have no idea what could
actually cause the counter to become unreliable so just always return
FALSE for the disjoint part.

The new code makes the shader cache manages all shaders and be able to upload
all of them to a caller-provided bo as a whole.
Previously, we uploaded only the bound shaders. When a different set of
shaders is bound, we had to allocate a new kernel bo to upload if the current
one is busy.

We need to set up a handler for the global_remove event that gets sent
out when a global gets removed. Without the handler we end up calling
a NULL pointer.

When rendering to a texture with BaseLevel set, the miptree may be laid
out such that BaseLevel is in level 0 of the miptree (to avoid wasting
memory on unused levels between 0 and BaseLevel-1). In that case, we
have to shift our render target's level down to the appropriate level of
the smaller miptree.
The WebGL test in combination with a meta code relating to
glGenerateMipmap also triggered a similar failure scenario.
This GPU hang regression was introduced by c754f7a8.

This reverts commit 41966fdb3b.
While it's a lot cleaner it causes regressions because
the draw interface is always called from the draw functions
of the drivers (because the buffers need to be mapped) which
means that the stream output buffers endup being cleared on
every draw rather than on setting.

Also add minimal support for occlusion predicate, though it can't be active
at the same time as an occlusion query yet.
While here also switchify some large if-else (actually just mutually

For conditional rendering this makes it possible to skip rendering
if either the predicate is true or false, as supported by d3d10
(in fact previously it was sort of implied skip rendering if predicate
is false for occlusion predicate, and true for so_overflow predicate).
There's no cap bit for this as presumably all drivers could do it trivially
(but this patch does not implement it for the drivers using true
hw predicates, nvxx, r600, radeonsi, no change is expected for OpenGL
functionality).

We're going to add more BCS_SWCTRL setup instances soon, and you have to
be careful to have the set and restore atomic with the rendering that's
done, so that our state doesn't leak out to other rendering processes.
v2: Rewrite the patch to have batch begin/advance macros so that magic
numbers don't get sprinkled around (and so you don't mix up your
do-I-need-to-reset vs what-do-I-reset-to logic, which I nearly did in
the next patch when first writing it)

Intel had brokenness here, and I'd like to continue moving Mesa toward
hiding 1D_ARRAY's ridiculousness inside of the core, like we did with
MapTextureImage. Fixes copyteximage 1D_ARRAY on intel.
There's still an impedance mismatch in meta when falling back to read and
texsubimage, since texsubimage expects coordinates into 1D_ARRAY as
(width, slice, 0) instead of (width, 0, slice).
v2: Fix offset of scanline reads from the source. (Thanks Brian!), replace
dd.h comment with Paul's text and replace early exit with an assert.

Primitive restart with an arbitrary cut index was first supported as of
Haswell. It's very doubtful that they'd take that away in future
hardware, so we may as well alter the check now.
The PRM suggests a larger layout, mostly to support having

Just use the same layout for both Gen4 and Gen5.
