e5423bb129 pan/bi: Do not cull post-RA staging writes 
Bifrost post-RA dead code elimination can cull the destinations of
regular ALU instructions, by weakening from a register write to a
temporary write. However, there is no way to suppress staging writes, so
culling the destinations will result in invalid code generation.

Fixes a regression in
dEQP-GLES3.functional.shaders.switch.switch_in_for_loop_static_vertex
with scoreboarding. The root cause there is the backend dead code
elimination not being sufficiently aggressive in the presence of control
flow. Usually this does not matter, since the backend optimizations are
intended to be local with global optimizations happening in NIR.
Unfortunately, our implementation of IDVS hits this hard. That will need
to be optimized (probably by specializing IDVS shaders in NIR instead of
the backend). In the mean time, let's fix the actual bug affecting
scoreboarding.

No shader-db changes.

87d46f40c8 pan/bi: Cull DTSEL_IMM dests in post-RA DCE 
They are useless (given the semantics of DTSEL_IMM) and complicate
scoreboarding. Just remove them in the pass that removes all the other silly
register destinations.

956b969616 pan/bi: Clarify requirement for barriers 
Barriers need to wait on all outstanding messages. This is more of an API
requirement than a hardware requirement, but it's still an invariant the
scoreboarding pass must respect.

a8418abd74 pan/bi: Revert "Fix load_const of 1-bit booleans" 
This reverts commit 29d319c767.

Now that we use nir_lower_bool_to_bitsize, we don't see 1-bit booleans
anymore, so the issue this fixed doesn't apply. Actually, that issue was
(in part) why I started looking into boolean handling in the first
place.

21bdee7bcc pan/bi: Switch to lower_bool_to_bitsize 
Instead of ingesting 1-bit booleans and trying to force everything to be
16-bit, except when it isn't, and creating a mess in the backend... just
use the NIR pass designed to select bitsize for booleans. Yes, this
means we need to handle more NIR instructions, but the handling is
easier and the conversion is more obvious (except for some edge cases
like 16-bit vectorized b32csel). This generates noticeably better code,
and the generated code will be easier to optimize.

f7d44a46cd pan/bi: Optimize replication 
Bifrost's 16-bit support comes in the form of vectorized instructions,
so when we manipulate scalars, we usually replicate to both bottom and
top halves of 32-bit registers. Add an analysis pass that detects
replication. Then, use that replication pass to optimize out useless
swizzle instructions (by changing them to plain moves, which can be
copypropped).

This optimization is a slight shader-db win on its own, and allows us to
transition to lower_bool_to_bitsize without regressing shader-db.

8bd4976d98 pan/bi: Lower swizzles on CSEL.i32/MUX.i32 
This is counter-intuitive, but required for correct operation when
CSEL.i32 takes a 1-bit (stored 16-bit) boolean argument. The impedance
mismatch ultimately is between CSEL.b32 (nir's bcsel, nonexistant in the
hardware) and the lowering CSEL.i32. However, a similar problem exists
even with MUX.i32 which lacks a good way of zero/sign-extending
booleans.

Cherry-picked from my Valhall branch though the issue also affects
Bifrost. Fixes piglit shaders@glsl-vs-if-bool on Bifrost.

Unfortunately, shader-db is quite unhappy :-(

The proper fix is to use lower_bool_to_bitsize, but that can't be
backported to mesa-stable.

a01b262990 nir: Add missing dependency on nir_opcodes.py 
Commit 38800b38 changed nir_opcodes.py, but that doesn't seem to have
triggered nir_opt_algebraic.py.  The change in 75ef5991 depends on
opt_algebraic lowering 16-bit versions of slt, but if opt_algebraic is
not rebuilt, this may not happen.  This resulted in some people seeing
assertion failures in, for example,
dEQP-VK.spirv_assembly.instruction.compute.float16.arithmetic_3.step,
due to the backend seeing nir_op_slt that it didn't know how to handle.

v2: Add nir_opcodes.py to nir_algebraic_py so that all the per-driver
algebraic passes pick up the dependency too.  Rename it to
nir_algebraic_depends.  Suggested by Emma.
