The only requirement for barriers is that the hardware doesn't support
allow_merging_workgroups with actual BARRIER instructions. We only emit
these for workgroup execution barriers though, so are safe to merge
workgroups when the shader uses memory barriers or subgroup execution
barriers.

This avoid unnecessarily emitting the switch back/away ambles when
they aren't actually used due to preemption optimization being
disabled. This alleviates unnecessary overhead when not running with
the mitigation for kernel drivers which support it.

KGSL doesn't support reading of performance counters by writing to
the selector registers directly from a userspace CS, instead these
requests need to be routed via the KGSL uAPI for perf counters.
Certain Turnip features which use performance counters such as
KHR_performance_query as well as preempt-optimize mode in autotune
are now explicitly disabled to reflect this.

For consistency with other shader stages (required by d3d, neither GL nor
Vulkan really care). A bit awkward since we don't want to disable them for
things like rusticl, which we should be able to distinguish with shader type.
Note that to satisfy d3d requirements, disabling denorms in general is not
sufficient, due to d3d requiring them to be disabled for single precision
opcodes, but enabled for double precision ones, and x86 can't switch that
individually (hence will need per-instruction tracking and switching inside
the shader).

Similar to what we already do for smallfloats to floats, handle denorms
and normals separately with bit manipulation stuff rather than rely on
a rescale mul which depends on cpu denorms.
This is a bit more complex, but on the upside we don't need to track
fpstate for denorms anymore in llvmpipe backend. (With modern x86 cpus
this is essentially only really relevant for r11g11b10 float format,
since f16 formats are using f16c instructions.)

isel.cf.deep_traversal is a new ACO test that verifies
that the iterative nir cf visitor allows arbitrary depth.
A depth of 10000 would cause a stack overflow on x86-64 linux
(4096 kB stack) for the old recursive code. This test
is by default not enabled.

When iterating control-flow recursively, we always run the
risk of causing a stack overflow if the control-flow
depth is too large. This patch resolves this by visiting
control-flow nodes in an iterative way, managing an explicit
stack on the heap.
