[llvm-dev] Review wanted - contribution for legacy pass manager (machine pass extensions)

[Arthur Eubanks via llvm-dev]

I'm not super familiar with the codegen pipeline, perhaps some backend
people can take a look?

A question is, do we want extensions like in the middle-end optimization
pipeline? I don't see why not, this mirrors the existing extensions for the
optimization pipeline. But it'd be good to get some more opinions from
people more knowledgeable.
