[Bug classpath/22768] gnu/java/security/util/Prime.java ignores return value of BigInteger methods

[gcc-bugzilla at gcc dot gnu dot org]

At 4 places in gnu/java/security/util/Prime.java, add is called on a BigInteger
as though it mutates the BigInteger it is invoked on (lines 58, 63, 79 and
125). 

BigInteger is immutable. Thus, methods such as BigInteger.add return a new
BigInteger, rather than mutating the BigInteger they are applied to.

I've checked in the fix.
