nvc0: reset the instanced elements state when doing blit using 3d engine
Since we update num_vtxelts here, we could otherwise end up with stale
instancing information in the upper bits which wouldn't otherwise get
reset. (Also we run the risk of the previous draw having set the first
element as instanced.)
This appears as one of the causes for the test pointed out in fdo#90363
to fail on nvc0.

nir/nir: Use a linked list instead of a hash set for use/def sets
This commit switches us from the current setup of using hash sets for
use/def sets to using linked lists. Doing so should save us quite a bit of
memory because we aren't carrying around 3 hash sets per register and 2 per
SSA value. It should also save us CPU time because adding/removing things
from use/def sets is 4 pointer manipulations instead of a hash lookup.
Running shader-db 50 times with USE_NIR=0, NIR, and NIR + use/def lists:
GLSL IR Only: 586.4 +/- 1.653833
NIR with hash sets: 675.4 +/- 2.502108
NIR + use/def lists: 641.2 +/- 1.557043
I also ran a memory usage experiment with Ken's patch to delete GLSL IR and
keep NIR. This patch cuts an aditional 42.9 MiB of ralloc'd memory over
and above what we gained by deleting the GLSL IR on the same dota trace.
On the code complexity side of things, some things are now much easier and
others are a bit harder. One of the operations we perform constantly in
optimization passes is to replace one source with another. Due to the fact
that an instruction can use the same SSA value multiple times, we had to
iterate through the sources of the instruction and determine if the use we
were replacing was the only one before removing it from the set of uses.
With this patch, uses are per-source not per-instruction so we can just
remove it safely. On the other hand, trying to iterate over all of the
instructions that use a given value is more difficult. Fortunately, the
two places we do that are the ffma peephole where it doesn't matter and GCM
where we already gracefully handle duplicates visits to an instruction.
Another aspect here is that using linked lists in this way can be tricky to
get right. With sets, things were quite forgiving and the worst that
happened if you didn't properly remove a use was that it would get caught
in the validator. With linked lists, it can lead to linked list corruption
which can be harder to track. However, we do just as much validation of
the linked lists as we did of the sets so the validator should still catch
these problems. While working on this series, the vast majority of the
bugs I had to fix were caught by assertions. I don't think the lists are
going to be that much worse than the sets.

i965/fs: Rework the fs_visitor LOAD_PAYLOAD instruction
The newly reworked instruction is far more straightforward than the
original. Before, the LOAD_PAYLOAD instruction was lowered by a the
complicated and broken-by-design pile of heuristics to try and guess
force_writemask_all, exec_size, and a number of other factors on the
sources.
Instead, we use the header_size on the instruction to denote which sources
are "header sources". Header sources are required to be a single physical
hardware register that is copied verbatim. The registers that follow are
considered the actual payload registers and have a width that correspond's
to the LOAD_PAYLOAD's exec_size and are treated as being per-channel. This
gives us a fairly straightforward lowering:
1) All header sources are copied directly using force_writemask_all and,
since they are guaranteed to be a single register, there are no
force_sechalf issues.
2) All non-header sources are copied using the exact same force_sechalf
and force_writemask_all modifiers as the LOAD_PAYLOAD operation itself.
3) In order to accommodate older gens that need interleaved colors,
lower_load_payload detects when the destination is a COMPR4 register
and automatically interleaves the non-header sources. The
lower_load_payload pass does the right thing here regardless of whether
or not the hardware actually supports COMPR4.
This patch commit itself is made up of a bunch of smaller changes squashed
together. Individual change descriptions follow:
i965/fs: Rework fs_visitor::LOAD_PAYLOAD
We rework LOAD_PAYLOAD to verify that all of the sources that count as
headers are, indeed, exactly one register and that all of the non-header
sources match the destination width. We then take the exec_size for
LOAD_PAYLOAD directly from the destination width.
i965/fs: Make destinations of load_payload have the appropreate width
i965/fs: Rework fs_visitor::lower_load_payload
v2: Don't allow the saturate flag on LOAD_PAYLOAD instructions
i965/fs_cse: Support the new-style LOAD_PAYLOAD
i965/fs_inst::is_copy_payload: Support the new-style LOAD_PAYLOAD
i965/fs: Simplify setup_color_payload
Previously, setup_color_payload was a a big helper function that did a
lot of gen-specific special casing for setting up the color sources of
the LOAD_PAYLOAD instruction. Now that lower_load_payload is much more
sane, most of that complexity isn't needed anymore. Instead, we can do
a simple fixup pass for color clamps and then just stash sources
directly in the LOAD_PAYLOAD. We can trust lower_load_payload to do the
right thing with respect to COMPR4.
