[Bug fortran/37832] New: System_Clock

Resolution of the System_Clock(TICKS,RATE,MAX) intrinsic degraded from about
3.6 MHz to 1,000 Hz when I upgraded from g77 to gfortran (for Windows).
There is a computer clock that I have accessed in Visual Basic that represents
elapsed time since my computer was turned on, returned as an integer*8
quantity, which operates at the higher frequency.
It should be possible for you to offer something similar by re-writing
System_Clock(TICKS,RATE,MAX) to operate at the higher frequency (as it was in
g77) and return TICKS as an integer*8.
