Fix statistics for x86 Windows builds

Using atomic_int_fast64_t variables with atomic functions on x86 does
not cause Visual Studio to report build errors, but such operations
yield useless results.  Since the isc_stat_t type is unconditionally
typedef'd to atomic_int_fast64_t, any code performing atomic operations
on isc_stat_t variables is broken in x86 Windows builds.  Fix by using
the atomic_int_fast32_t type for isc_stat_t in x86 Windows builds.

Note: BIND statistics counters are signed 64-bit values on
all platforms except one: 32-bit Windows, where they are
signed 32-bit values. Given that 32-bit values have a
vastly smaller range than 64-bit values, BIND statistics
counters in 32-bit Windows builds overflow significantly
more quickly than on all other platforms.
