In geometry shaders, calling EmitVertex() makes the contents of all
output variables undefined. We need to rewrite our layer ID and view
index outputs before each EmitVertex() call; assuming they'll preserve
their values is undefined behavior.

Currently, build_view_index and build_instance_id emit load_instance_id
intrinsics, which want the instance ID coming into the program, which is
the true instance ID multiplied by the view count.
The loop also remaps any load_instance_id in the original program back
to the true instance ID, which is the one coming in divided by the view
count. Because we call build_view_index and build_instance_id as part
of the loop, and emit the new load_instance_id instructions earlier in
the shader, we successfully avoid seeing those.
However, this is a bit fragile as it means you can't call
build_view_index or build_instance_id prior to the loop without
accidentally remapping things we don't intend to. To fix this
fragility, we save off the original instance ID (including the view
count) and directly reference that.

We were asserting that entry->dst.offset % REG_SIZE == 0, which is
easily tripped by a simple LOAD_PAYLOAD that writes a 16-bit vec2:
load_payload(8) vgrf1:UW, vgrf2+0.0:UW, vgrf3+0.0:UW
We create separate ACP entries corresponding to the values coming from
vgrf2 and vgrf3, with entry->dst set to the location within vgrf1 where
those sources get written to. So the second entry will have offset 16,
which is not REG_SIZE aligned.
It looks like this assert was originally added back in 2014 (see commit
1728e74957) and adjusted through the ages,
including at a point when we combined reg and subreg offsets into a
single byte offset, and over time also extended copy propagation.
Here the destination offset is already accounted for via rel_offset,
at the byte offset level, so things ought to work and there is no need
to assert that this is the case. Ian had already noted that the assert
tripped in commit e3f502e007, but checking
for inst->opcode == MOV here doesn't really make sense - it's just the
case that he found that broke.
Remove the erroneous assertion.

opt_copy_propagation() can sometimes propagate FIXED_GRF sources into
SHADER_OPCODE_SENDs as the message payload. For example, GS input
reads, which simply take a URB handle and have the offset in the
descriptor. For non-VGRFs, there isn't a payload to split, so just
skip past such send messages.

The 64-bit type lowering for SEL in opt_algebraic had a pre-existing bug
where it only triggered when 64-bit float _and_ integer types were
unsupported. Meteorlake supports 64-bit float but not integer, so we
need to lower Q/UQ in that case still.
When I moved this to a later pass, opt_peephole_sel started generating
Q/UQ SEL instructions which were failing to be lowered.

This is similar to what RADV implements using the NIR_LOOP_PASS
helpers. I have not used those helpers for a couple of reasons:
1. They use the pointer to the optimization function, which doesn't
work if the same function is called multiple times in one invocation
of the loop (fixable)
2. After fixing them, due to Intel's use of sub-expressions, the amount
of code added to wrap the shared macro becomes more than simply
reimplementing them for the Intel compiler
On most workloads the results are a wash, but on compile heavy
workloads like Cyberpunk 2077 and Rise of the Tomb Raider, I saw
fossil-db runtimes fall by 1-2% on my ICL, with no changes to the
compiled shaders. Caio saw closer to 2.5% on TGL.

Folks, there's more than one accumulator. In general, when the
register file is ARF, the upper 4 bits of the register number specify
which ARF, and the lower 4 bits specify which one of that ARF. This
can be further partitioned by the subregister number.
This is already mostly handled correctly for flags register, but lots
of places wanted to check the register number for equality with
BRW_ARF_ACCUMULATOR. If acc1 is ever specified, that won't work.
