Avoid unnecessary checking in getting current time on 32-bit systems. In ConvertTimespecToMicros(), int64_t is large enough to keep 32-bit time values in microseconds. The arithmetic checking for multiplication involves 64-bit division and can be slow. ConvertTimespecToMicros() is used by ClockNow(), and that can be used often.
