naruse 236b5e9778 * bignum.c (rb_big2ulong): the old logic seems to try to avoid 
calculating `-(long)(num-1)-1` if `num` is not LONG_MIN. (Note that
  `-LONG_MIN` may be larger than LONG_MAX) But C compilers can
  optimize it into single NEG instruction.
  Therefore those two conditions can be single if-body.

* bignum.c (rb_big2long): ditto.

* bignum.c (rb_big2ull): ditto.

* bignum.c (rb_big2ll): ditto.
