Fast Integers. The rep. of Integers is now data Integer = S# Int# | J# Int# ByteArray# - several new primops added for overflow-detecting arithmetic - negateInteger# removed; it can be done directly - integer_0, integer_1 etc. removed. - the compiler now uses S# where it previously used int2Integer. - the compiler generates small integers for -2^32 .. 2^32-1, instead of -2^29 .. -2^29-1. - PrelST.State datatype moved to LazyST (its only use). - some library code (in Time.lhs) still needs cleaning up, it depends on the Integer rep.
