The instruction and block lists are moved into a new "function definition"
struct, and the DXIL module tracks one at a time for adding instructions
into. The NIR side still only emits the main function here though.

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.
