Split the code dealing with IR and not touching native llvm into a separate package not depending on native llvm.

[KOLANICH]

The llvmlite.ir module contains classes and utilities to build the LLVM intermediate representation (IR) of native functions.

The provided APIs may sometimes look like LLVM’s C++ APIs, but they never call into LLVM, unless otherwise noted. Instead, they construct a pure Python representation of the IR.

Sounds like it can be possible.

@KOLANICH Can you outline the use case / motivation for this request? It's certainly possible, but why should it be done?

[KOLANICH]

I guess to allow the 2 parts be updated and used separately. I wonder if the pure python part can be used as a library for manipulating LLVM IR and then dumping them to disk, to be consumed by other tools that can work with the IR.
