anv: Remove all support for BufferViews

We never *actually* supported them, we just used them for binding UBOs.
Now that we have BufferInfo and we aren't supporting texture buffers yet,
we should get rid of them until we can do them properly.

anv/device: Only support binding UBOs through BufferInfo

anv: Rework UpdateDescriptorSets

Previously, UpdateDescriptorSets was wrong because it assumed that the
binding was the offset into the descriptor set.

anv: Add a descriptor_index to anv_descriptor_set_binding_layout

anv: Add a layout to anv_descriptor_set

anv/meta: Finish load clears for stencil attachments

Tested by Crucible "func.depthstencil.stencil_triangles.*" in

  commit c194292d5eadb84e9d7489fc01ce0b653cdd4ca5 (HEAD -> master)
  Author: Chad Versace <chad.versace@intel.com>

  Subject: func.depthstencil: Remove stencil clear workaround for Mesa

anv/cmd_buffer: Fix SURFACE_STATE for non-view buffer bindings

We were treating it as if it's a BufferView and weren't taking the offset
into account properly.

anv/cmd_buffer: Don't use an anv_state pointer in emit_binding_table

The anv_state is supposed to be a flyweight so we're not really saving
anything by using a pointer.  Also, we were creating one, setting a pointer
to it, and then having it go out-of-scope which is bad.

anv: Remove unused anv_render_pass members

Remove members
  num_color_clear_attachments
  has_depth_clear_attachment
  has_stencil_clear_attachment

The new clear code in anv_meta_clear.c does not use them.

anv/meta: Rewrite clear code

Fixes Crucible test "func.clear.load-clear.attachments-8".

The old clear code, when clearing attachments for
VK_ATTACHMENT_LOAD_OP_CLEAR, suffered from some fundamental bugs. The
bugs were not fixable with the old code's approach.

    - It assumed that a VkRenderPass contained at most one depthstencil
       attachment.

    - It tried to clear all attachments (color and the sole
      depthstencil) with a single instanced draw call, using the VUE
      header's RenderTargetArrayIndex to specify the instance's target
      color attachment. But the RenderTargetArrayIndex does not select
      entries in the binding table; it only selects an array index of
      a singled layered surface.

    - If at least one attachment of VkRenderPass had
      VK_ATTACHMENT_LOAD_OP_CLEAR,
      then the old code cleared *all* attachments. This was
      a consequence of using a single draw call and single pipeline for
      the clear.

The new clear code fixes those bugs by making a separate draw call for
each attachment, and using one pipeline when clearing color attachments
and a different pipeline for depth attachments.

The new code, like the old code, does not clear stencil attachments. It
is left as a FINISHME.

anv/meta: Clear color attribute is always flat

No behavioral change. This patch just removes an unneeded function
parameter.

anv/meta: Use consistent naming for dynamic state mask

Consistently rename bitmasks of Vulkan dynamic state to 'dynamic_mask'.

  anv_meta_saved_state::dynamic_flags -> dynamic_mask
  anv_meta_save(dynamic_state)        -> dynamic_mask

anv/meta: Rename anv_cmd_buffer_save/restore

As the functions are now exposed in anv_meta.h, let's rename them
to clarify that they are meta functions.

    anv_cmd_buffer_save -> anv_meta_save
    anv_cmd_buffer_restore -> anv_meta_restore

anv: Move meta clear code to new file anv_meta_clear.c

anv_meta.c currently handles blits, copies, clears, and resolves.  The
clear code is about to grow, and anv_meta.c is already busting at the
seams.

anv: Move struct anv_vue_header to anv_private.h

Move it from anv_meta.c to the common header anv_private.h. This allows
us to split the meta blit and meta clear code into separate files.

Merge remote-tracking branch 'mesa-public/master' into vulkan

nir: remove sampler_set from nir_tex_instr

Now that descriptor sets are handled in a lowering pass, this is no longer
needed.

i965/gen8+: Extract color clear surface state

On future generation platforms the color clear value is stored elsewhere in the
surface state. By extracting this logic, we can cleanly implement the difference
in an upcoming patch.

Should have no functional impact.

i965/gen8+: Remove redundant zeroing of surface state

gallium/swrast: fix front buffer blitting. (v2)

So I've known this was broken before, cogl has a workaround
for it from what I know, but with the gallium based swrast
drivers BlitFramebuffer from back to front or vice-versa
was pretty broken.

The legacy swrast driver tracks when a front buffer is used
and does the get/put images when it is mapped/unmapped,
so this patch attempts to add the same functionality to the
gallium drivers.

It creates a new context interface to denote when a front
buffer is being created, and passes a private pointer to it,
this pointer is then used to decide on map/unmap if the
contents should be updated from the real frontbuffer using
get/put image.

This is primarily to make gtk's gl code work, the only

i965/sched: use liveness analysis for computing register pressure

Previously, we were using some heuristics to try and detect when a write
was about to begin a live range, or when a read was about to end a live
range. We never used the liveness analysis information used by the
register allocator, though, which meant that the scheduler's and the
allocator's ideas of when a live range began and ended were different.
Not only did this make our estimate of the register pressure benefit of
scheduling an instruction wrong in some cases, but it was preventing us
from knowing the actual register pressure when scheduling each
instruction, which we want to have in order to switch to register
pressure scheduling only when the register pressure is too high.

This commit rewrites the register pressure tracking code to use the same
model as our register allocator currently uses. We use the results of
liveness analysis, as well as the compute_payload_ranges() function that
we split out in the last commit. This means that we compute live ranges
twice on each round through the register allocator, although we could
speed it up by only recomputing the ranges and not the live in/live out
sets after scheduling, since we only shuffle around instructions within
a single basic block when we schedule.

Shader-db results on bdw:

total instructions in shared programs: 7130187 -> 7129880 (-0.00%)
instructions in affected programs: 1744 -> 1437 (-17.60%)

i965: always run the post-RA scheduler

Before, we would only do scheduling after register allocation if we
spilled, despite the fact that the pre-RA scheduler was only supposed to
be for register pressure and set the latencies of every instruction to
1. This meant that unless we spilled, which we rarely do, then we never
considered instruction latencies at all, and we usually never bothered
to try and hide texture fetch latency. Although a later commit removes
the setting the latency to 1 part, we still want to always run the
post-RA scheduler since it's able to take the false dependencies that
the register allocator creates into account, and it can be more
aggressive than the pre-RA scheduler since it doesn't have to worry
about register pressure at all.
