After 3ecd357d81, it may be possible for
the VS to get assigned all of the URB space.
On Ivy Bridge, this will cause the offset for the other stages to be
16, which cannot be packed into the ConstantBufferOffset field of
3DSTATE_PUSH_CONSTANT_ALLOC_*.
Instead we can set the offset to zero if the stage size is zero.

This allows us to avoid doing some unneeded work on the meta paths where we
know that the image view will be used for exactly one thing. The meta
paths also sometimes do things that aren't quite valid like setting the
array slice on a 3-D texture and we want to limit the number of paths that
need to be able to sensibly handle the lies.
If you have an out-of-tree build, gen8_pack.h and friends will not be in
the same folder as genX_pack.h so this will be a problem. We fixed
out-of-tree earlier by adding the genxml folder to the includes for the
vulkan driver. However, this is not a good long-term solution because we
want to use it in ISL as well.
Consecutive tiles are separated by the size of the tile, not by the
logical tile width.

Previously we allocated 4kB of push constant space for VS, GS, and PS
(for a total of 12kB) no matter what. This works, but doesn't fully
utilize the space - we have 16kB or 32kB of space.
This makes anv use the same method as brw - divide up the space evenly
among all active shader stages. This means HS and DS would get space,
if those shader stages existed.
In the future, we can probably do better by inspecting how many push
constants each shader stage uses, and weight things accordingly. But
this is strictly better than the old code, and ideally we'd justify
a fancier solution with actual performance data.
Rather than keeping separate {vs,hs,ds,gs}_start fields, we now store an
array indexed by the shader stage (MESA_SHADER_*). The 3DSTATE_URB_*
commands are also sequentially numbered. This makes it easy to just
emit them in a loop.
This simplifies the code a little, and also will make it easier to add
more credible HS and DS code later.
Not called from any other file. Remove _mesa_ prefix and update comments.

The change "mesa/readpix: Don't clip in _mesa_readpixels()" caused a
few piglit regressions. The failing tests use glReadPixels to read
from the front color buffer. The problem is we were trying to read
from a non-existant front color buffer. The front color buffer is
created on demand in st/mesa. Since the missing buffer bounds were
effectively 0 x 0 the glReadPixels was totally clipped and returned
early.
The fix involves creating the real front color buffer when we're about
to try reading from it.
Tested with llvmpipe and VMware driver on Linux, Windows.

Unfortunately, glslang gives us cull/clip distance and GS streams even if
the shader doesn't use it whenever a shader is declared as version 450.
This is a glslang bug, but we can easily enough ignore it for now.
The descriptor sizes array gives the total number of each type of
descriptor that will ever be allocated from the pool, not the total amount
that may be in any particular set. In our case, this simply means that we
have to sum a bunch of things up and there we go.
We can't use a global descriptor pool like we were because it's not
thread-safe. For now, we'll allocate them on-the-fly and that should work
fine. At some point in the future, we could do something where we
stack-allocate them or allocate them out of one of the state streams.
The current code in r600_translate_colorswap uses the swizzle information
to determine which colorswap to use.
This works for BE & LE when the nr_channels is <4, but when nr_channels==4
(e.g. PIPE_FORMAT_A8R8G8B8_UNORM), this method can not be used for both BE
and LE, because the swizzle info is the same for both of them.
As a result, r600g doesn't support 24bit color formats, only 16bit, which
forces the user to choose 16bit color in X server.
This patch fixes this bug by separating the checks for LE and BE and
adapting the swizzle conditions in the BE part of the checks.

"st/mesa: overhaul vertex setup for clearing, glDrawPixels, glBitmap"
added a vertex shader declaring IN[0] and IN[2], but not IN[1].
Drivers relying on tgsi_shader_info can't handle holes in declarations,
because tgsi_shader_info doesn't track that.
This is just a quick workaround meant for stable that will work for vertex
shaders.
