Fix some instances of 4 bytes = 32 bits assumption.

* hash.c (equal_hash, eql_hash, cobj_eq_hash_op,
hash_hash_op): Multiply object size by CHAR_BIT and switch on
number of bits, rather than bytes.

* sysif.c (off_t_num): Likewise.

* arith.c, ffi.c, itypes.c, rand.c: In numerous #if directive,
fix size tests from bytes to bits.

* configure: in the test that detects integer types, and in
the test for enabling large file offsets, detect one more
variable from the system: the value of CHAR_BIT. This
turns into SIZEOF_BYTE. We use that value instead of a
hard-coded 8.
