re PR rtl-optimization/20756 (Clobbers of deleted insns are processed, but left out)
PR rtl-optimization/20756:
* basic-block.h (PROP_DEAD_INSN): Define.
* flow.c (propagate_one_insn): Set during mark_set_regs call
for a dead insn.
(mark_set_1): Emit a clobber when we are about to delete a dead insn
that kills a live register.
