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.

This is support-code to emit the DirectX Intermediate Language, which is
a dialect of LLVM 3.7 bitcode. Because modern versions of LLVM doesn't
support emitting bitcode for older versions, and we can't rely on an old
LLVM version because we need the OpenCL support from Clang later on, we
instead implement our own LLVM bitcode encoder as part of this work.
See the official DXIL documentation for more details on DXIL:
https://github.com/Microsoft/DirectXShaderCompiler/blob/master/docs/DXIL.rst
The reason this comes as a separate library, is because we're also using
this code as the basis for an OpenCL C compiler, which will follow as a
separate merge-request later.
This is the combination of more than 230 commits from our development
branch, including the work from several authors.
