  Changed paths:
    A llvm/test/tools/llvm-reduce/mir/instr-reduce-dead-def.mir
    M llvm/tools/llvm-reduce/deltas/ReduceInstructionsMIR.cpp

  Log Message:
  -----------
  llvm-reduce: Do not insert replacement IMPLICIT_DEFs for dead defs

Also skip dead defs when looking for a previous vreg with the same
class. This helps avoid some mid-reduction verifier errors when
LiveIntervals computation starts introducing dead flags everywhere.
