(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. Differential Revision: https://reviews.llvm.org/D110527
