These are both handled by inserting them directly at the top of the
nir_function_impl. However, if the cursor is already at the top, it
never gets updated so we end up inserting other stuff after the newly
inserted undef or decl_reg. It's an odd edge case to be sure but I hit
it with my new NIR CF pass for NAK.

The varying linker isn't changed. The passes are executed after linking
varyings and before linking uniforms if nir->options->lower_io_variables
is true. nir_opt_varyings can move uniforms between shaders and cause them
to be DCE'd.
It requires moving IO deref lowering from st/mesa into the GLSL linker
and nir_opt_varyings should be added at the same time because IO deref
lowering alone would disable IO optimizations in st/mesa such as
compaction.

Highlights:
- all shader stages and all input/output types are handled, including
inputs and outputs with multiple vertices
- the optimizations performed are: unused input/output removal, constant
and uniform propagation, output deduplication, inter-shader code motion,
and compaction
- constant and uniform propagation and output deduplication work even
if a shader contains multiple stores of the same output, e.g. in GS
- the same optimizations are also performed between output stores and
output loads (for TCS)
- FS inputs are packed agressively. Only flat, interp FP32, and interp
FP16 can't be in the same vec4. Also, if an output value is
non-divergent within a primitive, the corresponding FS input is
opportunistically promoted to flat.

explanation, which is the same as:

Instead of the previous fragile attempt to handle sparse_resident_and
by crawling deref chains, we now insert an is_sparse_resident_zink
intrinsic immediately after the tex or sparse_load intrinsic and define
Zink's sparse resident codes to always be 0/1. Then sparse_resident_and
becomes iand and is_sparse_texels_resident becomes != 0 and everything
is well-defined and robust.

Unlike in GLSL IR it is illegal to add an instruction to a block
following a jump in NIR. Here we add code to the glsl_to_ir pass
to remove any such instructions before they are processed i.e.
we remove them as soon as we process the jumps.
Handling this in glsl to nir allows us to avoid depending on the
lower_jumps() pass being called directly before glsl to nir when
it otherwise doesn't need to be called an additional time.

were rename that version to visit_exec_list_safe() and create
a version that calls the non-safe foreach call.
There are only 2 users of visit_exec_list() we change lower_jumps
to use the renamed version and leave glsl_to_nir() to use the
non-safe version as it never deletes the current instruction and
in the following patch we will add code that may delete the next
instruction meaning the safe version would be unsafe to use.
