During TSC synchronization test, use rdtsc() rather than rdtsc32(), to
protect against 32-bit TSC overflow while the sync test is running.

On dual-socket Xeon E5-2600 (SNB) systems with up to 32 threads, there
is non-trivial chance (2-3%) that TSC synchronization test fails due to
32-bit TSC overflow while the synchronization test is running.
