with vtn_bindgen2 we only care about a single function at a time, not a whole
nir_shader, and it would be quite wasteful to serialize all the shader info
every time. add a specialized serialize just for 1 function.

It's not at all clear how this pass should work with real function calls (if at
all), but at least this is enough to handle collections of self-contained
functions which vtn_bindgen2 wants.

Annotating ssa defs without affecting compilation is impossible with
debug info instructions since referencing a nir_def from the debug info
instr will add uses.
The old approach also stops worrking if passes reorder instructions.
This patch proposes a solution which should not regress performance just
like the old approach. The difference is that this one allocates a bit
more space for debug info instead of adding a new instruction for it.

We will lower polygon stipple before we have si_shader_args, so we need
an intrinsic to get the buffer descriptor.

Liveness info can be huge, since with larger shaders it essentially
grows quadratically (linear increase in number of SSA defs *
linear increase in blocks).
Freeing liveness info early helps somewhat mitigate memory usage here.

From OpenGL 4.6 - 8.23.1 Depth Texture Comparison Mode
Let Dt be the depth texture value and St be the stencil index
component. If there is no stencil component, the value of St is
undefined. Let Dref be the reference value, provided by the shader’s
texture lookup function. If the texture’s internal format indicates
a fixed-point depth texture, then Dt and Dref are clamped to the
range [0, 1]; otherwise no clamping is performed.

..where N = # of functions in the shader. We were accidentally reprocessing the
whole shader for every function impl. Noticed when reading a vtn_bindgen2
profile.
We elect to port the relevant part of the pass to instrctions_pass which fixes
the perf problem while deleting a pile of code.
