Provide faster bignum-in-fixed-integer range tests in MPI.
* mpi/mpi.c (mp_in_range, mp_in_intptr_range,
mp_in_uintptr_range): New functions.
* mpi/mpi.h (mp_in_range, mp_in_intptr_range,
mp_in_uintptr_range): Declared.
* arith.c (NUM_MAX_MP, INT_PTR_MAX_MP, UINT_PTR_MAX_MP,
INT_PTR_MAX_SUCC_MP): Static variables removed. Note that
INT_PTR_MAX_MP was not used at all!
(normalize): Use mp_in_range instead magnitude comparison to
NUM_MAX_MP.
(in_int_ptr_range, in_uint_ptr_range): Static functions removed.
(c_unum): Use mp_in_uintptr_range instead of
in_uint_ptr_range.
(arith_init): Remove initializations of removed variables.
(arith_free_all): Remove cleanup of removed variables, leaving
function empty.
* lib.c (c_num): Use mp_in_intptr_range instead of
in_int_ptr_range.
