cpu: Adding GUPSGen ClockedObject.
This patch adds the code base to implement GUPSGen which is a
ClockedObject that creates read/write requests to the memory
to update elements in an array. The choosing of elements in
the array follow a random distribution. Each element is read
from and return as GUPSGen implements a key-value store program.
Specifications are found in HPCC website from RandomAccess
benchmark. link below.
