* fold-const.c (int_const_binop_1): Use op1.mul_with_sign (op2, ...)
instead of op1 - op2.  Pass 2 * TYPE_PRECISION (type) as second
argument to rshift method.  For 2 * HOST_BITS_PER_WIDE_INT precision
use wide_mul_with_sign method.

* gcc.dg/vect/pr56918.c: New test.
* gcc.dg/vect/pr56920.c: New test.
