intel/fs: Use ALIGN16 instructions for all derivatives on gen <= 7
The issue here was discovered by a set of Vulkan CTS tests:
dEQP-VK.glsl.derivate.*.dynamic_*
These tests use ballot ops to construct a branch condition that takes
the same path for each 2x2 quad but may not be uniform across the whole
subgroup. They then tests that derivatives work and give the correct
value even when executed inside such a branch. Because the derivative
isn't executed in uniform control-flow and the values coming into the
derivative aren't smooth (or worse, linear), they nicely catch bugs that
aren't uncovered by simpler derivative tests.
Unfortunately, these tests require Vulkan and the equivalent GL test
would require the GL_ARB_shader_ballot extension which requires int64.
Because the requirements for these tests are so high, it's not easy to
test on older hardware and the bug is only proven to exist on gen7;
gen4-6 are a conjecture.

v3d: take into account separate_stencil when checking if stencil should be cleared
In most cases this is not needed because the usual is that when a
separate stencil is written, the parent resource is also written.
This is needed if we have a separate stencil, no depth buffer, and the
source and destination is the same, as in that case the stencil can be
updated, but not the parent source (like if you are blitting only the
stencil buffer). On that situation, the following access to the
stencil buffer would clear the stencil buffer (so overwritting the
previous blitting) cleared because the parent source has
v3d_resource.writes to 0.
As far as I see, that situation only happens with the
GL_DEPTH32F_STENCIL8 format.
Note that one alternative would consider that if the separate_stencil
has been written, the parent should also be considered written (and
update its "writes" field accordingly). But I found this patch more
natural.

nir/find_array_copies: Handle wildcards and overlapping copies
This commit rewrites opt_find_array_copies to be able to handle
an array copy sequence with other intervening operations in between. In
particular, this handles the case where we OpLoad an array of structs
and then OpStore it, which generates code like:
foo[0].a = bar[0].a
foo[0].b = bar[0].b
foo[1].a = bar[1].a
foo[1].b = bar[1].b
...
that wasn't recognized by the previous pass.
In order to correctly handle copying arrays of arrays, and in particular
to correctly handle copies involving wildcards, we need to use a tree
structure similar to lower_vars_to_ssa so that we can walk all the
partial array copies invalidated by a particular write, including
ones where one of the common indices is a wildcard. I actually think
that when factoring in the needed hashing/comparing code, a hash table
based approach wouldn't be a lot smaller anyways.
All of the changes come from tessellation control shaders in Strange
Brigade, where we're able to remove the DXVK-inserted copy at the
beginning of the shader. These are the result for radv:

lima/gpir/sched: Don't try to spill when something else has succeeded
In try_node(), we assume that the node we pick can still be scheduled
successfully after speculatively trying all the other nodes. Normally we
always undo every node after speculating it, so that when we finally
schedule best_node the scheduler state is exactly the same and it
succeeds. However, we also try to spill nodes, which can change the
state and in a corner case that can make scheduling best_node fail. In
particular, the following sequence of events happened with piglit
shaders@glsl-vs-if-nested: a partially-ready node N was spilled and a
register store node S, which is a use of N, was created and then later
the other uses of N were scheduled, so that S is now ready and N is
partially ready. First we try to schedule S and succeed, then we try to
schedule another node M, which fails, so we try to spill the remaining
uses of N. This succeeds, but scheduling M still fails so that best_node
is still S. However since one of the uses of N is one cycle ago, and
therefore we inserted a read dependent on S one cycle ago when spilling
N, S can no longer be scheduled as read-after-write latency is three
cycles.
While we could ad-hoc try to catch cases like this, or (the best option
but very complicated) treat the spill as speculative and roll it back if
we decide not to schedule the node, a simpler solution is to just
give up on spilling if we've already successfully speculatively
scheduled another node. We'd give up a few cases where we discover that
by spilling even harder we could schedule a more desirable node, but
that seems like it would be pretty rare in practice. With this we
guarantee that nothing has been touched after best_node was successfully
scheduled. We also cut down on pointless spilling, since if we already
scheduled a node it's unlikely that spilling harder will let us schedule
an even better node, and hence any spilling at this point is probably
useless.
While we're here, clean up the code around spilling by flattening the
two if's and getting rid of the second unnecessary check for INT_MIN.
