We need to force persample shading when
a) shader uses sample_id
b) shader uses sample_position
c) shader uses sample qualifier.
Also since ps_iter_samples can now change independently of the
rasterizer samples we need to move setting the regs more often.

In commit 45cd76e342 schedule_instructions(bblock_t *) began
setting bblock_t::cycle_count, but that function was not called on
trivial blocks.
Remove the code to skip trivial blocks so that cycle_count is set.

schedule_instructions(bblock_t *) isn't called on blocks with a single
instruction, and since it is the only thing that set cycle_count,
cycle_count would be uninitialized.
A non-empty block with bblock_t::cycle_count == 0 is arguably a bug.
That'll be fixed in the next commit.

Debugging a shader-db reported cycle count regression from the tex
coalescing, I eventually figured out that the texture latencies were
totally bogus. Really fixing it will probably involve mirroring
vc4_qir_schedule.c's texture fifo management here.
This isn't as complete as I would like (can't merge interpolation because
of the implicit r5 dependency, doesn't work with control flow), but this
was cheap and easy.

The VPM write logic will be basically the same as the texture coordinate
write logic we need, and it's not really related to the VPM read logic
other than the reuse of the use_count array.
Every caller was dereffing the qinst, and this will let us make the number
of sources vary depending on the destination of the qinst so that we can
have general ALU ops that store to tex_[strb] and get an implicit uniform.
This may have made a tiny bit of sense when we had one 4-arg inst per
shader, but if we only ever put 2 things in, having a pointer to 2 things
almost every instruction is pointless indirection.
This matches what NVIDIA and AMD hardware expose, as well as what Intel
hardware supports.

Previously, we had an OFFSET_VALUE source for logical texture instructions
that was intended to mean exactly what it says, "offset". In reality, we
only fully used it for tg4 offsets. We used offset_value.file == IMM to
mean, "you have a constant offset, go look in instr->offset" and didn't
actually use the contents of the register at all in that case except for
in nir_emit_texture where we used it as a temporary before we copy it into
instr->offset.
This commit renames OFFSET_VALUE to TG4_OFFSET and restricts its usage to
indirect tg4 offsets only. The nir_emit_texture code is refactored so that
we explicitly build a header_bits value which is placed in instr->offset
and the constant offset values (both for tg4 and regular texture
operations) are used to construct header_bits and don't go through the
offset source at all. Finally, we stop passing offset_value in to
lower_sampler_logical_send_gen5 because we can't do indirect offsets until
gen7 anyway.

07fe2d565b introduced a big hack in order to return
NumSubroutineUniforms when querying ACTIVE_RESOURCES for
<shader>_SUBROUTINE_UNIFORM interfaces. However this is the
wrong fix we are meant to be returning the number of active
resources i.e. the count of subroutine uniforms in the
resource list which is what the code was previously doing,
anything else will cause trouble when trying to retrieve
the resource properties based on the ACTIVE_RESOURCES count.
The real problem is that NumSubroutineUniforms was counting
array elements as separate uniforms but the innermost array
is always considered a single uniform so we fix that count
instead which was counted incorrectly in 7fa0250f9.
Idealy we could probably completely remove
NumSubroutineUniforms and just compute its value when needed
from the resource list but this works for now.

The 1-D special case doesn't actually apply to depth or HiZ. I discovered
this while converting BLORP over to genxml and ISL. The reason is that the
1-D special case only applies to the new Sky Lake 1-D layout which is only
used for LINEAR 1-D images. For tiled 1-D images, such as depth buffers,
the old gen4 2-D layout is used and the QPitch should be in rows.
