Some bits were already there for texture views but some were missing.
In particular for cube map views things needed to change a bit.
For simplicity I ended up removing the separate face addr bit (just use
the z bit) - cube arrays didn't use it already, so just follow the same
logic there. (In theory using separate bits could allow for better hash
function but I don't think anyone ever did some measurements of that so
probably not worth the trouble, if we'd reintroduce it we'd certainly
wanted to use the same logic for cube arrays and cube maps.)
Also extend the seamless cube sampling to cube arrays - as there were no
piglit failures before this is apparently untested, but things now generally
work quite the same for cube textures and cube array textures so there
hopefully shouldn't be any trouble...
49 new piglits, 47 pass, 2 fail (both due to fake multisampling).
v2: incorporate Brian's feedback, add sampler view validation,
function rename, formatting fixes.

All the functionality was pretty much there, just not tested.
Trivially fix up the missing pieces (take target info from view not
resource), and add some missing bits for cubes.
Also add some minimal debug validation to detect uninitialized target values
in the view...
49 new piglits, 47 pass, 2 fail (both related to fake multisampling,
not texture_view itself). No other piglit changes.
v2: move sampler view validation to sampler view creation, update docs.

i965: Fix PBO cache coherency issue after _mesa_meta_pbo_GetTexSubImage().
This problem can easily be reproduced with a number of
ARB_shader_image_load_store piglit tests, which use a buffer object as
PBO for a pixel transfer operation and later on bind the same buffer
to the pipeline as shader image -- The problem is not exclusive to
images though, and is likely to affect other kinds of buffer objects
that can be bound to the 3D pipeline, including vertex, index,
uniform, atomic counter buffers, etc.

i965: Use predicate enable bit for conditional rendering w/o stalling
Previously whenever a primitive is drawn the driver would call
_mesa_check_conditional_render which blocks waiting for the result of
the query to determine whether to render. On Gen7+ there is a bit in
the 3DPRIMITIVE command which can be used to disable the primitive
based on the value of a state bit. This state bit can be set based on
whether two registers have different values using the MI_PREDICATE
command. We can load these two registers with the pixel count values
stored in the query begin and end to implement conditional rendering
without stalling.
Unfortunately these two source registers were not in the whitelist of
available registers in the kernel driver until v3.19. This patch uses
the command parser version from intel_screen to detect whether to
attempt to set the predicate data registers.
The predicate enable bit is currently only used for drawing 3D
primitives. For blits, clears, bitmaps, copypixels and drawpixels it
still causes a stall. For most of these it would probably just work to
call the new brw_check_conditional_render function instead of
_mesa_check_conditional_render because they already work in terms of
rendering primitives. However it's a bit trickier for blits because it
can use the BLT ring or the blorp codepath. I think these operations
are less useful for conditional rendering than rendering primitives so
it might be best to leave it for a later patch.
v2: Use the command parser version to detect whether we can write to
the predicate data registers instead of trying to execute a
register load command.
v3: Simple rebase
v4: Changes suggested by Kenneth Graunke: Split the
load_64bit_register function out to a separate patch so it can be
a shared public function. Avoid calling
_mesa_check_conditional_render if we've already determined that
there's no query object. Some styling fixes.

i956: Add a function to load a 64-bit register from a buffer
Adds brw_load_register_mem64 which is similar to brw_load_register_mem
except that it queues two GEN7_MI_LOAD_REGISTER_MEM commands in order
to load both halves of a 64-bit register. The function is implemented
by splitting the 32-bit version into an internal helper function which
takes a size.
This will later be used to set the 64-bit predicate source registers.

i965: Store the command parser version number in intel_screen

It was possible for some events never to get triggered if one thread
was creating events and another threads was waiting for them.
This patch consolidates soft_event::wait() and hard_event::wait()
into event::wait() so that hard_event objects will now wait for
all their dependencies to be submitted before flushing the command
queue.
v2:
- Rename variables
- Use mutable varibales so we can keep event::wait() const
- Open code signalled() call so mutex can be atted to signalled
without deadlocking.
