In DXIL, the FMA instruction only supports 64-bit operations. However,
back when we implemented support for this, there were only a single
switch for lowering all ffma instructions, so we couldn't easily use it.
But now that there's separate flags to lower ffma on 16, 32 and 64 bit,
we can lower 16 and 32 bit ffmas, and leave 64 bit ffmas alone.

When I originally added the FFMA opcode here, I added the FMAD opcode
instead of the FMA opcode. The reason for this is that it works on
32-bit values as well, so that seemed like a better fit.
But that's not correct, as the FMA opcode isn't a fused operation, so
let's correct the opcode.
This isn't currently in use, because we currently lower away all ffma
opcodes on the NIR level, but that's about to change.
While we're at it, let's also update the opcode name to match the DXIL
documentation.

Most of these are adding 'static', for functions that are local
to a translation unit but weren't declared static.
There's one instance of a missing include for bringing the prototype
into the translation unit, one function missing a return type (default-int),
and one which added inline to avoid it being considered unused in some sources.

This wasn't implemented yet, because we hadn't encountered it yet. But
now it seems we can trigger this, thanks to the nv_copy_depth_to_color
piglit tests.
This makes the test go from crash to fail, which isn't perfect, but it's
better than nothing.

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.

This fixes a regression that happened after rebasing on master, where we
end up not writing all components of the clip-distance array, which the
DXIL validation code in the D3D12 runtime treats as an error.
To ensure we don't end up overwriting a previous wrire, enable
nir_shader_compiler_options::lower_all_io_to_temps as well.

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.

containing code by several authors.
