We already mark all fragment shaders as always using blend constants so
this is handled by the existing code and our setting of push.count.
Also, this hack is wrong as it pushes way too much and might overflow
memory. Also, it will overflow the HW limit of 64 as soon as we
increase the size of panvk_graphics_sysvals.

Otherwise, we'll only mark the first location for matrix and array

I'm not sure if this is the best way to enforce this as it's really a
restriction on the blend array pointer. Individual blend descriptors
only have to be 16B-aligned. But this seems to work and doesn't affect
the array stride, which is still 16B.
Also, I couldn't actually find the restriction in the v10 docs but it's
there on v11 and this is enough of a pain to debug that we're probably
better off playing it safe.

This is what the JM code is doing and it lets us assume we always have a
fragment shader. Right now, we're already making that assumption, we
just haven't been bitten by it yet because no one has tried to use a
shader-requiring blend configuration with no FS yet.

On Bifrost, we have to return the blend return offset in the compiled
shader info and that means we need to be able to index into an array by
blend target deep inside the compiler. Instead of assuming bound blend
targets and subtracting BIR_FAU_BLEND_0 from fau_idx, add a separte
blend_target to bi_instr and use that. This way what we return will be
based on the nir_io_semantics::location, regardless of where the actual
blend descriptor comes from.

Since the move to MEMORY_*_LOGICAL the result value was being ignored, so
change to use that.
Since the conversion to use new registers, some issues were introduced:
- Even with `has_64bit_int` ADD with 64-bit immediate value is not supported;
- `dst_high` was not being filled if there was no overflow;
- Only `dst_low` returned.
Found when writing some new code involving large block loads.

This catches a number of bugs in the current NIR algebraic optimizations
or opcodes implementations (as fixed in this series, or documented in the
XFAIL tests), and should prevent many future bugs from landing.
This required bumping the test timeout, because s390x is very slow to

nir_algebraic_pattern_test can validate shaders with the following
structure:
%0 = @provide(base = 0)
...
%N = @provide(base = input_count)
// multiple equivalent expressions
a = ...
b = ...
valid = ieq(a, b)
@use(valid)
Expressions are evaluated by emulating the shader using

When calculating the relative offset for a branch the pco_first_igrp
function is used to find the first instruction of a block.
However if the block is empty the function does not return NULL as it
description implies but returns a pointer to the list head which is not a
valid node. Using this leads to a garbage relative offset been calculated
which leads to unexpected behaviour.
Fix is to add a check for the list been empty and return NULL (the same
issue also exists in pco_last_igrp). This leads to the calling function,
pco_cf_node_offset, searching for the next none empty block which is the
expected behaviour.
