base,mem: Support AtomicOpFunctor in the classic memory system
AtomicOpFunctor can be used to implement atomic memory operations.
AtomicOpFunctor is captured inside a memory request and executed directly
in the memory hierarchy in a single step.
This patch enables AtomicOpFunctor pointers to be included in a memory
request and executed in a single step in the classic cache system.
This patch also makes the copy constructor of Request class do a deep
copy of AtomicOpFunctor object. This prevents a copy of a Request object
from accessing a deleted AtomicOpFunctor object.
