[Diffusion] rL237954: Resubmit r237708 (MIR Serialization: print and parse LLVM IR using MIR format).

[Alex L]

Hi,

I'm not sure if it would possible to break this circular dependency.

LLVMMIR has to depend on LLVMCodeGen as it needs to access all the machine
IR state.
But at the same time LLVMCodeGen has to connect to LLVMMIR to create a
printing pass and
then later to parse the machine functions, as llc does all the pass setup
with LLVMCodeGen.

If this dependency is a problem maybe LLVMMIR should be a part of
LLVMCodeGen?

Alex.
