For D3DUSAGE_AUTOGENMIPMAP basically, everything behaves
for the application as if the texture had one level.
However the pipe_resource has more levels, and those
get generated automatically.
Previously we did allocate all the Surfaces as if
the texture had all the levels, except of just one.
The app could still just access the first level.
This patch completly removes the useless unaccessible
Surfaces.
In addition removes redundant handling of D3DUSAGE_AUTOGENMIPMAP.

This reverts commit 1a0b0e8460.
The bounds checking behaviour of ds_read_b64, ds_read_b96 and ds_read_b128
make this feature very difficult to use safely.
This fixes a blocking artifact in Hitman 2. Previously, it contained:
ds_read_b64(local_invocation_index() * 4 - 4)
For local_invocation_index()=0, the second dword would be considered
out-of-bounds, even though it's at offset 0.

Now that we can pipeline all varyings we should not be referring
specifically to smooth varyings anywhere.
Also, rename the instruction field 'ldvary_pipelining' to
'is_ldvary_sequence', which is more appropriate, since we always
set this for any instruction involved with varying setups,
independently of whether they end up being pipelined or not.
This also does some other minor edits which intend to slightly
simplify the code and make it a bit more compact.

An earlier commit tried to make this shader compatible with GLSL 3.30,
but it requires, GL_ARB_gpu_shader_int64, which requires GLSL 4.00 and
GL 4.0 according to the extension spec. So we were failing to enable
the required extension, breaking compilation of this shader.
The original intention of that patch was to get this working on zink,
which at the time only supported GL 3.3. But now it supports later
OpenGL versions, so we don't need to do this any longer. Rather than
revert the patch and raise the version all the way back to 430, just
bump it to the require 400 at Ian Romanick's suggestion.

These end up having a NOP between the ldvary and the next instruction
in the sequence (a MOV for flat and an FADD for noperspetive):
nop ; nop ; ldvary.r0
nop ; nop
fadd rf6, r0, r5 ; nop ; ldvary.r1
nop ; nop
fadd rf5, r1, r5 ; nop ; ldvary.r2
nop ; nop
fadd rf4, r2, r5 ; nop ; ldvary.r3
To pipeline these, we can reuse the same infrastructure we have in
place for smooth varyings but we need to avoid breaking the sequence
due to the NOP instruction. We do that by testing if dropping the
sequence when we failed to pick up the next instruction also fails
to choose an instruction.
This is not perfect, because we may be able to choose an instruction
outside the sequence such as an ldunif, and use that to break a
sequence that we could otherwise continue after scheduling the NOP
instruction, but it is still better than nothing.

Typically, we would schedule smooth varyings like this:
nop ; nop ; ldvary.r4
nop ; fmul r0, r4, rf0
fadd rf13, r0, r5 ; nop ; ldvary.r1
nop ; fmul r2, r1, rf0
fadd rf12, r2, r5 ; nop ; ldvary.r3
nop ; fmul r4, r3, rf0
fadd rf11, r4, r5 ; nop ; ldvary.r0
where we pair up an ldvary with the fadd of the previous sequence
instead of the previous fmul. This is because ldvary has an implicit
write to r5 which is read by the fadd of the previous sequence, so
our dependency tracking doesn't allow us to move the ldvary before the
fadd, however, the r5 write of the ldvary instruction happens in the
instruction after it is emitted so we can actually move it to the fmul
and the r5 write would still happen in the same instruction as the fadd,
which is fine.
This patch allows us to pipeline these sequences optimally. For that,
after merging an ldvary into a previous instruction in the middle of
a pipelineable ldvary sequence, we check if we can manually move it
to the last scheduled instruction instead (the one before the
instruction we are currently scheduling).
If we are successful at moving the ldvary to the previous instruction,
then we flag the ldvary as scheduled immediately, which may promote
its children (the follow-up fmul instruction for that ldvary) to DAG
heads and continue the merge loop so that fmul can be picked and
merged into the final fadd of the previous sequence (where we had
originally merged the ldvary). This leads to a result that looks like
this:
nop ; nop ; ldvary.r4
nop ; fmul r0, r4, rf0 ; ldvary.r1
fadd rf13, r0, r5 ; fmul r2, r1, rf0 ; ldvary.r3
fadd rf12, r2, r5 ; fmul r4, r3, rf0 ; ldvary.r0

If we have two (or more) smooth varyings like this:
nop t3; ldvary.rf0
fmul t5, t3, t0
fadd t6, t5, r5
nop t7; ldvary.rf0
fmul t9, t7, t0
fadd t10, t9, r5

fadd rf12, r2, r5 ; fmul r4, r3, rf0 ; ldvary.r0
But in order to do this, we will need to manually tweak the
QPU scheduling.
This patch tracks information about ldvary sequences that are
good candidates for pipelining, and a follow-up patch will
use this information to pipeline them when we emit the QPU
code.

- Rename the v3d_compile fields to avoid confusion with the qinst fields.

When selecting an instruction to merge, we want to pre-remove that
instruction from the DAG, not the one we are merging it in, which
we had already pre-removed right before.
The reason this was not causing problems before is that the
consequence of this bug is we will choose the same instruction
again in the merge loop and trying to merge that instruction twice
will fail and we would break out of the merge loop and move on.

EXT_external_objects require we call glSignalSemaphoreEXT followed by a
glFlush. If the rendering workload is small when Signal and Flush
take place the relevant batch buffers with the actual rendering might
have been submitted already. In that case the following condition is met:
(iris_batch_bytes_used(batch) == 0). This causes:
glFlush() --> iris_fence_flush() -> iris_batch_flush() ->
_iris_batch_flush() to no-op, and so the fence doesn't get submitted to the
kernel. Then when anv tries to submit an execuf2 that must wait on the
shared VkSempahore / drm_syncobj fence, there isn't one and the kernel
rejects the batchbuffer causing an -EINVAL return of the execbuf2 ioctl
and a VK_DEVICE_LOST error. Empty batch buffers do have typically one
fence attached, but the ones carrying the extra fence from a
glSignalSempahore() call do have at least 2.
See also: the discussion in MR!4337.

A sequence like:
1) create sampler view CSO with UBWC resource
2) later create another sampler view or image view with the same
resource, but a format that triggers demoting the resource to
uncompressed
3) bind CSO created in step #1
would not work correctly, because the CSO created in step #1 is still
setup for UBWC, despite the fact that the resource had been demoted to
uncompressed.
Fortunately this is easy enough to detect, as the resource's seqno would
have been updated.
