A large integer is currently represented as a pair of HOST_WIDE_INTs.
It therefore represents a number with precision of
2 * HOST_BITS_PER_WIDE_INT bits (it is however possible that the
internal representation will change, if numbers with greater precision
are needed, so the users should not rely on it).  The representation does
not contain any information about signedness of the represented value, so
it can be used to represent both signed and unsigned numbers.  For
operations where the results depend on signedness (division, comparisons),
it must be specified separately.  For each such operation, there are three
versions of the function -- double_int_op, that takes an extra UNS argument
giving the signedness of the values, and double_int_sop and double_int_uop
that stand for its specializations for signed and unsigned values.

You may also represent with numbers in smaller precision using double_int.
You however need to use double_int_ext (that fills in the bits of the
number over the prescribed precision with zeros or with the sign bit) before
operations that do not perform arithmetics modulo 2^precision (comparisons,
division), and possibly before storing the results, if you want to keep
them in some canonical form).  In general, the signedness of double_int_ext
should match the signedness of the operation.

??? The components of double_int differ in signedness mostly for
historical reasons (they replace an older structure used to represent
numbers with precision higher than HOST_WIDE_INT).  It might be less
confusing to have them both signed or both unsigned.
