cb884d8ab2 freedreno/ir3: use nopN encoding when possible
Use the (nopN) encoding for slightly denser shaders.. this lets us fold
nop instructions into the previous alu instruction in certain cases.

Shouldn't change the # of cycles a shader takes to execute, but reduces
the size.  (ex: glmark2 refract goes from 168 to 116 instructions)

Currently only enabled for a6xx, but I think we could enable this for
a5xx and possibly a4xx.

6dabcb5bcf mesa: fix display list corner case assertion
This fixes a failed assertion in glDeleteLists() for the following
case:

list = glGenLists(1);
glDeleteLists(list, 1);

when those are the first display list commands issued by the
application.

When we generate display lists, we plug in empty lists created with
the make_list() helper.  This function uses the OPCODE_END_OF_LIST
opcode but does not call dlist_alloc() which would set the
InstSize[OPCODE_END_OF_LIST] element to non-zero.

When the empty list was deleted, we failed the InstSize[opcode] > 0
assertion.

Typically, display lists are created with glNewList/glEndList so we
set InstSize[OPCODE_END_OF_LIST] = 1 in dlist_alloc().  That's why
this bug wasn't found before.

To fix this failure, simply initialize the InstSize[OPCODE_END_OF_LIST]
element in make_list().

The game oolite was hitting this.

fd37a19ac4 i965: fixed clamping in set_scissor_bits when the y is flipped
Calculating the scissor rectangle fields with the y flipped (0 on top)
can generate negative values that will cause assertion failure later on
as the scissor fields are all unsigned. We must clamp the bbox values
again to make sure they don't exceed the fb_height. Also fixed a
calculation error.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108999
          https://bugs.freedesktop.org/show_bug.cgi?id=109594

v2:
   - I initially clamped the values inside the if (Y is flipped) case
   and I made a mistake in the calculation: the clamp of the bbox[2] should
   be a check if (bbox[2] >= fbheight) bbox[2] = fbheight - 1 instead and I
   shouldn't have changed the ScissorRectangleYMax calculation. As the
   fixed code is equivalent with using CLAMP instead of MAX2 at the top of
   the function when bbox[2] and bbox[3] are calculated, and the 2nd is more
   clear, I replaced it. (Nanley Chery)

v3:
   - Reversed the CLAMP change in bbox[3] as the API guarantees that the
   viewport height is positive. (Nanley Chery)

v4:
  - Added nomination for the mesa-stable branch and the link to the second
  bugzilla bug (Nanley Chery)

9646750822 vulkan/overlay: fix includes
The Loader/Validation-Layers repository allow the user to choose where
header files are installed. On my system I choose /usr/include
thinking it was the obvious "base" location, but it turns out the
headers end up being installed right there rather in a vulkan
subdirectory. On Debian/Ubuntu the selected installation path is
/usr/include/vulkan, so just go with that.

Hopefully other distro don't choose another path.

Note that the validation layer doesn't provide a .pc file so we have
no way of querying where the headers are installed.

97566efe5c v3d: Rematerialize MOVs of uniforms instead of spilling them.
If we have a MOV of a uniform value available to spill, that's one of our
best choices.  We can just not spill the value, and emit a new load of the
uniform as the fill.  This saves bothering the TMU and the thrsw, and is
the same cost in uniforms (since the spill offset is a uniform anyway).

This doesn't have a huge impact on shader-db, since there aren't a whole
lot of spills and we usually copy-prop the uniforms at the VIR level such
that the only uniform MOVs are from vir_lower_uniforms:

total instructions in shared programs: 6430292 -> 6430279 (<.01%)
total uniforms in shared programs: 2386023 -> 2385787 (<.01%)
total spills in shared programs: 4961 -> 4960 (-0.02%)
total fills in shared programs: 6352 -> 6350 (-0.03%)

However, I'm interested in dropping the uniforms copy-prop in the backend,
since it would be cheaper to not load repeated uniforms if we have the
registers to spare.  This also saves many spills on
dEQP-GLES31.functional.ubo.random.all_per_block_buffers.20, which is what
motivated a bunch of my recent backend work in the first place:

before: 46 spills, 106 fills, 3062 instructions
after: 0 spills, 0 fills, 2611 instructions

875942c059 mesa/core: Enable EXT_depth_clamp for GLES >= 2.0
The extension NV_depth_clamp is written against OpenGL 1.2.1, and
since GLES 2.0 is based on GL 2.0 there is no reason not to enable
this extension also for GLES >= 2.0.

v2: Use EXT_depth_clamp that has been proposed to Khronos

v3: - Fix check for extension availability (Erik Faya-Lund)
    - Also fix the test in is_enabled
v4: - Test both, ARB and EXT extension (Erik)
v5: - Fix white space errors (Erik)
