Starting work on adding bit operations. The semantics is that
negative integers behave as an "infinite bit two's complement".
* arith.c (logand, logor, logxor): New functions.
* eval.c (eval_init): New intrinsic functions logand, logior, logxor.
* lib.h (logand, logor, logxor): Declared.
* mpi-patches/series: New patch, add-bitops.
* mpi-patches/add-bitops: New file.
