misc: Adding GUPSGen to components library.
This change adds GUPSGenCore, GUPSGen, GUPSGenEP, and GUPSGenPAR.
GUPSGenCore inherits from AbstractGeneratorCore. It is used for
implementing GUPSGen, GUPSGenEP, and GUPSGenPAR which inherit from
AbstractProcessor. GUPSGen does not implement a multi-core
generator as there are two ways to implement GUPS in parallel.
GUPSGenEP implement GUPS in it Embarrassingly Parallel variant
where multiple instances of GUPS update separate partitions of the
memory. GUPSGenPAR impelements GUPS in its Parallel variant where
multiple generators acccess the same partition of the memory in
parallel.
