c5e64c041f nir/lower_io_to_scalar: Convert to use nir_shader_instructions_pass().
This unindents a whole bunch of code, and fixes the lack of metadata
tracking in the pass (which wasn't called in an opt loop so it hadn't been
caught before).

d29f10a7ca nir: add nir_intrinsic_interp_deref_at_vertex
From the SPV_AMD_shader_explicit_vertex_parameter extension:
   "Returns the value of the input <interpolant> without any
    interpolation, i.e. the raw output value of previous shader
    stage."

867fe35a16 nir/lower_io_to_scalar: Look at derefs for modes
This is instead of looking all the way back to the variable which may
not exist for all derefs.  This makes this code properly ignore casts
with modes other than the mode[s] we care about (where casts aren't
allowed).

8265dfaa87 nir: Allow using nir_lower_io_to_scalar_early on VS input vars.
This will be used on V3D to cut down the size of the VS inputs in the VPM
(memory area for sharing data between shader stages).

d80c342d89 nir: add deref lowering sanity checking
This will be removed at the end of the transition, but add some tracking
plus asserts to help ensure that lowering passes are called at the
correct point (pre or post deref instruction lowering) as passes are
converted and the point where lower_deref_instrs() is called is moved.

6af5e0bec9 nir: add variant of lower_io_to_scalar to be called earlier
This is intended to be called before nir_lower_io() so that we
can do some linking optimisations with the results. It can also
be used with drivers that don't use nir_lower_io() at all such
as RADV.

v2: pass mode mask rather than first and last stage integer.

0320bb2c6c nir: Use nir_src_copy instead of direct assignments.
If the source is an indirect register, there is ralloc'd data.  Copying
with a direct assignment will copy the pointer, but the data will still
belong to the old instruction's memory context.  Since we're lowering
and throwing away instructions, that could free the data by mistake.

Instead, use nir_src_copy, which properly handles this.

This is admittedly not a common case, so I think the bug is real,
but unlikely to be hit.

9f1411d1ec nir: Add an IO scalarizing pass using the intrinsic's first_component.
vc4 wants to have per-scalar IO load/stores so that dead code elimination
can happen on a more granular basis, which it has been doing in the
backend using a multiplication by 4 of the intrinsic's driver_location.
We can represent it properly in the NIR using the first_component field,
though.
