Description

Speed up rbigint operations by everything from 5% to 40% (I managed to get one pow test down from 17.8s to 10.2s). It also add some special cases for BIGINT0, BIGINT1, BIGINT*powerOfTwo, BIGINT-BIGINT and BIGINT+BIGINT (these things happends internally on all operations, so it causes a general speed gain).

Haven't tried any benchmark out of rpython.
