When a kernel input is a pointer to global or constant memory, it's expected
that the invoker provides the pointer value in the form of
(buffer_index << 32) | offset. The buffer index, however, is statically
knowable in the compiler, as long as a buffer is bound. Since it's
undefined behavior to dereference the pointer with no buffer bound,
we can replace any deref chain that terminates in an access with one
that uses a constant buffer index.

Instead, we replace every use of it with nir_def. Most of this commit
was generated by sed:
sed -i -e 's/dest.ssa/def/g' src/**/*.h src/**/*.c src/**/*.cpp
A few manual fixups were required in lima and the nir_legacy code.

We could add a nir_def_num_components() helper but we use
ssa.num_components about 3x as often as nir_dest_num_components() today
so that's a major Coccinelle refactor anyway and this doesn't make it
much worse. Most of this commit was generated byt the following
semantic patch:
@@
expression D;
@@
<...
-nir_dest_num_components(D)
+D.ssa.num_components
...
Some manual fixup was needed, especially in cpp files where Coccinelle
tends to give up the moment it sees any interesting C++.

nir_builder_at requires a block to chase back to the function impl,
but for an empty function impl, the previous code produced a cursor
with a null pointer. It was also just extra complicated.
While I'm here, use the new foreach helper since this code needs an impl.

It doesn't depend on the clc data being provided externally, so no
need to tie it there, we can re-use it for GL and Vulkan compute.

This adds a standalone library which can convert through the pipeline of
OpenCL C -> SPIR -> SPIR-V -> NIR -> DXIL. It can add in the libclc
implementations of various library functions in the NIR phase, and
also massages the NIR to shift it more towards graphics-style compute.
This is leveraged by the out-of-tree OpenCLOn12 runtime
(https://github.com/microsoft/OpenCLOn12).
This is the combination of a lot of commits from our development branch,
containing code by several authors.
