For instruction sequences that change the address register with every load
the current limit to bail out of the scheduler and reject the optimisation
was too tight, i.e. it was expected that at least one pending instruction
would be scheduled each time.
Give the scheduler more margin to sort out these load sequences by allowing
a number of rounds where no instruction is scheduled.

This patch is based on
https://lists.freedesktop.org/archives/mesa-dev/2018-February/185805.html
Dave Airlie:
"A bunch of CTS tests led me to write
tests/shaders/ssa/fs-while-loop-rotate-value.shader_test
which r600/sb always fell over on.
GCM seems to move some of the copies into other basic blocks,
if we don't allow this to happen then it doesn't seem to schedule
them badly.
Everything I've read on SSA/phi copies say they have to happen
in parallel, so keeping them in the same basic block seems like
a good way to keep some of that property."
This patch differs from the one proposed by Dave in that it only adds
the NF_DONT_MOVE flag to copy_move instructions that are created by split_phi*
and that are located in loops.
Fixes piglit: tests/shaders/ssa/fs-while-loop-rotate-value.shader_test
(no regressions in the shader set). It also fixes all failing tests from
dEQP-GLES3.functional.shaders.loops.*

This was mistakenly exposed, even though we want atomic counters to be
lowered to atomic ops on an SSBO like nearly every other GPU. Which
somehow recently started getting segfaults due to calling a null
pipe->set_hw_atomic_buffers().
Fixes a crash in stk, and probably other things.

vc4+vc5 is not really effected by the deref chain to deref instr
conversion, so it no longer needs this pass. For others, now that
all the passes mesa/st uses are using deref instructions, push the
lowering to deref chains back into driver.

To simplify the transition, and make things bisectable, split out a
legacy copy or lower_samplers. This way the i965 and gallium drivers
can independently switch over to deref instructions.
Since the lower_samplers_as_deref pass is only used by gallium drivers,
it can be converted in lock-step with moving the lower_deref_instrs
pass, and so does not need a corresponding _legacy clone.
This legacy pass will be removed in a future commit.

This pass doesn't handle deref instructions yet. Making it handle both
legacy derefs and deref instructions would be painful. Since it's not
important for correctness, just disable it for now.

fix spilling regression introduced by 5428066f5e
this is just a minor mistake done while moving the code out into a new

earlier and skipped setting noSpill to 1. After the refactoring it was always
set.
