Variables spilled on both branch legs need to be assigned to the same spilling slot.
These affinities can be transitive through multiple merge blocks.

This patch makes the live variable analysis more precise
w.r.t. killed phi operands and the block's register pressure.

Converting to 'Conventional SSA Form' ensures correctness w.r.t. spilling of phi nodes.
Previously, it was possible that phi operands have intersecting live-ranges, and thus,
couldn't get spilled to the same spilling slot. For this reason, ACO tried to avoid to
spill phis, even if it was beneficial.
This patch implements a conversion pass which is currently only called if spilling is necessary.

Winsys semaphores without signal operation get silently ignored.
Not so for syncobjs, so actually signal them.

Previously, the scheduler tried to move up instructions from below depending
VMEM instructions only to move them down again when scheduling the VMEM
instruction.
Reviewed-by: Rhys Perry <pendingchaos02@gmail.com>
These got lost due to some refactoring.
Due to the way our scheduler works currently, for now
we add back the reorder flag for divergent loads only.

This patch changes VMEM scheduling in a way that they can only
be moved upwards by previous VMEM instructions but not downwards.
This way, it improves the order of VMEM instructions in relation
to their users.

Previously, we allowed all shaders to reduce the number of max_waves to as low as 5.
Restricting this on shaders with low register demand, increases the total number of waves
while the VMEM def-use distances hardly change.
This patch also changes the max number of move operations per MEM instruction.

This is actually a non-threaded implementation. I'd summarize this
as event-based submission.
When submit happens we walk a tree of submissions that depend on
the syncobj signal operations to be submitted and if those submission
we no other dependencies we start to execute them immediately.
Or, well I still use a list to avoid issues with long chains and
the stacksize when using recursion.

This does not fully do wait-before-submit, to be done in a follow
up patch.
For kernels without support for timeline syncobjs, this adds an
implementation of non-shareable timelines using legacy syncobjs.

This is a function with timeout support for reading from the pipe
between processes used for secure compile.
Initially we hardcode the timeout to 5 seconds. We can adjust the
timeout limit in future if needed.

Previously subgroup shuffle was implemented using the bpermute
instruction, which only works accross half-waves, so by itself it's
not suitable for implementing subgroup shuffle when the shader is
running in wave64 mode.
This commit adds a trick using shared VGPRs that allows to implement
subgroup shuffle still relatively effectively in this mode.
