vc4: Add kernel support for branching in shader validation.

We're already checking that branch instructions are within the
contents of the shader and the proper PROG_END sequence is present.
The other thing we need in the presence of branching is to verify that
the shader doesn't overflow past the end of the uniforms stream.

To do that, we require that at the start of any basic block reading
uniforms have the following instructions:

load_imm temp, <offset within uniform stream>
add unif_addr, temp, unif

The instructions are generated by userspace, and the kernel verifies
that the load_imm is of the expected offset, and that the add adds it
to a uniform.  We track which uniform in the stream that is, and at
draw call time fix up the uniform stream to have the address of the
start of the shader's uniforms for that draw call.

vc4: Add a bitmap of branch targets in kernel validation.

This isn't used yet, it's just a first step toward loop validation.
During the main parsing of instructions, we need to know when we hit a new
basic block so that we can reset validated state.

vc4: Track the current instruction into the validation_state.

This reduces how much we need to pass around as arguments, which was
becoming more of a problem with looping validation.

vc4: Add QPU support for generating BRANCH instructions.

vc4: Print live variable start/ends during QIR dumping.

This only happens when live variables are set up, which is not in the
normal dump, but is set up when we've failed to register allocate.

vc4: Implement live intervals using a CFG.

Right now our CFG is always a trivial single basic block, but that will
change when enable loops.

vc4: Make vc4_qir_schedule handle each block in the program.

Basically we just treat each block independently.  The only inter-block
scheduling I can think of that would be be interesting would be to move
texture result collection to after a short loop/if block that doesn't do
texturing.  However, the kernel disallows that as part of its security
validation.

vc4: Convert uniforms lowering to work with multiple blocks.

We still decide which uniform to lower based on how many
instructions-that-need-lowering use that uniform, but now we emit a new
temporary uniform load in each of the basic blocks containing an
instruction being lowered.

This commit is best reviewed with diff -b.

vc4: Convert vc4_opt_peephole_sf to work with control flow.

We need to apply the peephole pass to each of the blocks in the program.
We don't do dataflow analysis for SF across blocks, but we also don't
generate code that would need us to do so.

vc4: Create a basic block structure and move the instructions into it.

The optimization passes and scheduling aren't actually ready for multiple
blocks with control flow yet (as seen by the "cur_block" references in
them instead of iterating over blocks), but this creates the structures
necessary for converting them.

vc4: Add a "qir_for_each_inst_inorder" macro and use it in many places.

We have the prior list_foreach() all over the code, but I need to move
where instructions live as part of adding support for control flow.  Start
by just converting to a helper iterator macro.  (The simpler
"qir_for_each_inst()" will be used for the for-each-inst-in-a-block
iterator macro later)

vc4: Also enable phi elimination.

This avoids a bunch of code gen regressions when enabling loops in vc4.

Prior to that, the GLSL that would have generated these optimizable phi
nodes was being lowered to csels between either (undef, a) or (a, a), and
those were being dealt with by nir_opt_undef and nir_opt_algebraic.

vc4: fix memory leak

The allocation has succeeded by that point, so it needs to be freed.

st/omx/dec: convert decoder video buffer to progressive

with encode tunneling

The idea of encode tunneling is to use video buffer directly for encoder,
but currently the encoder doesn’t support interlaced surface, the OMX
decoder set progressive surface before on that purpose.

Since now we are polling the driver for interlacing information for
decoder, we got the interlaced as preferred as other APIs(VDPAU, VA-API),
thus breaking the transcode with tunneling.

The solution is when with tunnel detected, re-allocate progressive target
buffers, and then converting the interlaced decoder results to there.

This has been tested with transcode results bit to bit matching as before
with surface from progressive to progressive.

nvc0: fix the driver cb size when draw parameters are used

The size of the driver constant buffer for each stage should be 2048
and not 512 because it has been increased recently for buffers/images.
While we are at it, do the same change for indirect draws.

This fixes all ARB_shader_draw_parameters tests on GM107.

gallium/u_queue: guard fence->signalled checks with fence->mutex

I have seen a hang during application shutdown that could be explained by the
following race condition which this patch fixes:

1. Worker thread enters util_queue_fence_signal, sets fence->signalled = true.
2. Main thread calls util_queue_job_wait, which returns immediately.
3. Main thread deletes the job and fence structures, leaving garbage behind.
4. Worker thread calls pipe_condvar_broadcast, which gets stuck forever because
   it is accessing garbage.
