src/cpu/SConscript:
Add memtester to the compilation environment.
Someone who knows this better should make the MemTest a cpu model parameter.
For now attached with the build of o3 cpu.
src/cpu/memtest/memtest.cc:
src/cpu/memtest/memtest.hh:
Update Memtest for new mem system
src/python/m5/objects/MemTest.py:
Update memtest python description
