[Bug middle-end/37359] [4.4 Regression] IRA miscompiled transfer.o in libgfortran, sejmp

[hjl dot tools at gmail dot com]

regstat_compute_ri has

  /* See the setjmp comment in regstat_ri_bb_compute.  */
  EXECUTE_IF_SET_IN_BITMAP (setjmp_crosses, FIRST_PSEUDO_REGISTER, regno, bi) 
    {
      REG_BASIC_BLOCK (regno) = REG_BLOCK_UNKNOWN;
      REG_LIVE_LENGTH (regno) = -1; 
    }     

But IRA never uses REG_LIVE_LENGTH.
