* basic-block.h (PROP_ALLOW_CFG_CHANGES): Define.
(PROP_FINAL): Include PROP_ALLOW_CFG_CHANGES.
(propagate_block): Update prototype.
* flow.c (update_life_info): Simplify the CFG and
recalculate the global regs which are alive when
removing dead code during a global update.
(propagate_block): Return non-zero if an INSN is
deleted.
