This patch moves the calculation of current uniforms to
link_uniforms, which makes use of UniformRemapTable which
stores all the reserved uniform locations.
Location assignment for implicit uniforms now tries to use
any gaps left in the table after the location assignment
for explicit uniforms. This gives us more space to store more
uniforms.
Patch is based on earlier patch with following changes/additions:
1: Move the counting of explicit locations to
check_explicit_uniform_locations and then pass
the number to link_assign_uniform_locations.
2: Count the number of empty slots in UniformRemapTable
and store them in a list_head.
3: Try to find an empty slot for implicit locations from
the list, if that fails resize UniformRemapTable.
Fixes following CTS tests:
ES31-CTS.explicit_uniform_location.uniform-loc-mix-with-implicit-max
ES31-CTS.explicit_uniform_location.uniform-loc-mix-with-implicit-max-array

This basically saves the current pipeline state, sets up state for
rendering, constructs a set of textured quads, renders, then restores
the previous pipeline state.
It shouldn't be hard to implement a similar function for non-gallium
drives. With some code refactoring, the vertex definition code could
probably be shared.

This improves the performance of applications which use glXUseXFont()
or wglUseFontBitmaps() and glCallLists() to draw bitmap text.
Basically, we collect all the glBitmap images from the display lists
and put them into a texture atlas. To render the bitmaps for a
glCallLists() command, we render a set of textured quads where each
quad is textured with one bitmap image. Actually, the rendering part
has to be done by the Mesa driver or Mesa/gallium state tracker.
Note that GLUT demos that use glutBitmapCharacter() don't benefit
from this.
v2, per Nicolai Hähnle:
- check the max tex rect size is at least 1024.
- add comment in dd.h that texture_rectangle is required.
- in _mesa_DeleteLists(), try to delete the atlas before the list(s)

This gives us the chance to pack the binding table down to just what the
shaders actually need. Some applications use very large descriptor sets
and only ever use a handful of entries. Compacted binding tables should be
much more efficient in this case. It comes at the down-side of having to
re-emit binding tables every time we switch pipelines, but that's
considered an acceptable cost.
We ignore unused dimensions in the isl surface; do the same for the
resulting anv_image.

"Result is the same as computing the sum of the absolute values of

We were doing sum of absolute values of OpDPdx of P and OpDPdx of NULL.
We don't need to look at the stage flags, as we don't really support any
fine-grained, stage-level synchronization. We have to do two
PIPE_CONTROLs in case we're both flushing and
invalidating.
Additionally, if we do end up doing two PIPE_CONTROLs, the first,
flusing one also has to stall and wait for the flushing to finish, so we
don't re-dirty the caches with in-flight rendering after the second
PIPE_CONTROL invalidates.
Every stage has a corresponding 3DSTATE_CONSTANT_XS packet, so having
the code to create and emit push constant buffers in genX_vs_state.c
is a little strange. Moving it to a separate file seems more logical.

We would assert on unused dimensions (eg extent.depth for
VK_IMAGE_TYPE_2D) not being 1, but the specification doesn't put any
constraints on those. For example, for VK_IMAGE_TYPE_1D:
"If imageType is VK_IMAGE_TYPE_1D, the value of extent.width must be
less than or equal to the value of
VkPhysicalDeviceLimits::maxImageDimension1D, or the value of
VkImageFormatProperties::maxExtent.width (as returned by
vkGetPhysicalDeviceImageFormatProperties with values of format,
type, tiling, usage and flags equal to those in this structure) -
whichever is higher"
We'll fix up the arguments to isl to keep isl strict in what it expects.
We need to make sure GEM understands that we're writing to the BO, in
case it needs to synchronize with other rings (blitter use in display
server, for example).
This will prevent optimization passes from introducing unsupported
library calls.

This seems to give more reliable results. More similar to what we do on
a3xx, although I think it breaks the a3xx theory that the four sets of
results map to each MRT (since we appear to still only have four sets on

Some hw queries need their sample memory locations to have certain
alignment. At the moment that isn't an issue, since the only hw query
is occlusion, so all samples have the same size. But when others are
added with different sample sizes, this starts to be a problem.
All current and immediately upcoming hw queries simply need their
sample address aligned to their size, so let's use that for now.
