Subject: * range.c (range_max): use FIX2LONG instead of FIX2INT to avoid  
 RangeError by ((-0x80000001)...(-0x80000001)).max on LP64.

* insns.def (opt_plus): use FIX2LONG instead of FIX2INT to avoid
  RangeError by 0x3fffffffffffffff+1 on LP64.

* insns.def (opt_succ): don't use 0x80000000 which assumes 32bit VALUE.
  use FIX2LONG instead of FIX2INT.
