Whenever we have an ALU op that's operating on a double, we'll unpack
it as an integer, then repack it as a float. When we have an ALU op that
returns a double, we'll unpack it as a double, then repack it as an integer.
Then, simple algebraic opts will remove any redundant unpack/repack ops,
so we should be left with constructing and deconstructing doubles using
the right operations.

As the pass's comment explains, NIR compact arrays are a better match
to represent the GLSL float[] design of clip/cull distance arrays, compared
to the float4[2] approach. This pass adjusts the variables to more closely
match what DXIL signatures would look like for that representation.

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.

Here's the code to emit DXIL code from NIR. It's big and bulky as-is,
and it needs to be split up a bit.
