  Recommit "[llvm-reduce] Add MIR support"

(Second try. Need to link against CodeGen and MC libs.)

The llvm-reduce tool has been extended to operate on MIR (import, clone and
export). Current limitation is that only a single machine function is
supported. A single reducer pass that operates on machine instructions (while
on SSA-form) has been added. Additional MIR specific reducer passes can be
added later as needed.
