(encode, decode): Use 4 HOST_WIDE_INTs for encoded value with HOST_BITS_PER_WIDE_INT/2 bits in each.
(encode, decode): Use 4 HOST_WIDE_INTs for encoded
value with HOST_BITS_PER_WIDE_INT/2 bits in each.
(LOWPART, HIGHPART): New macros.
(BASE): Move definition outside of div_and_round_double.
(add_double, mul_double, lshift_double, rshift_double): Rewrite.
(lrotate_double): Use LOWPART, HIGHPART, and BASE.
(rrotate_double): Likewise.
(div_and_round_double): Major changes to code for general case.
Now it actually produces non-garbage results for large operands.
(div_and_round_double): Simplify condition for special code used when
divisor < BASE.
(const_binop): Delete special cases for multiplying by 0, 1, 2, 4, 8.
(fold, case *_DIV_EXPR): Don't try to optimize for overflow.
