Alex Smith 5c7d52183c Implemented system_time() for x86_64.
* Uses 64-bit multiplication, special handling for CPUs clocked < 1 GHz
  in system_time_nsecs() not required like on x86.
* Tested against a straight conversion of the x86 version, noticably
  faster with a large number of system_time() calls.
