egl/sl: use kms_swrast with vgem instead of a random GPU

VGEM and kms_swrast were introduced to work with one another.

All we do is CPU rendering to dumb buffers. There is no reason to carve
out GPU memory, increasing the memory pressure on a device that could
make a better use of it.

Note:
 - The original code did not work out of the box, since the dumb buffer
ioctls are not exposed to render nodes.
 - This requires libdrm commit 3df8a7f0 ("xf86drm: fallback to MODALIAS

nir/spirv: return after emitting a branch in block

When emitting a branch in a block, it does not make sense to continue
processing further instructions, as they will not be reachable.

This fixes a nasty case with a loop with a branch that both then-part
and else-part exits the loop:

%1 = OpLabel
     OpLoopMerge %2 %3 None
     OpBranchConditional %false %2 %2
%3 = OpLabel
     OpBranch %1
%2 = OpLabel
    [...]

We know that block %1 will branch always to block %2, which is the merge
block for the loop. And thus a break is emitted. If we keep continuing
processing further instructions, we will be processing the branch
conditional and thus emitting the proper NIR conditional, which leads to
instructions after the break.

This fixes dEQP-VK.graphicsfuzz.continue-and-merge.

radv: Interpolate less aggressively.

Seems like dxvk used integer builtins without setting the flat
interpolation decoration.

I believe in the current spec the app is required to set these,
but in the meantime to avoid breaking things in stable releases
(and so close to release for 19.0), only expand the interpolation
to float16 and struct (which cannot be builtins as our spirv parser
lowers the builtin block).

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.

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)
