Update the Memtester, commit a config file/test for it.
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 --HG-- extra : convert_revision : d6a63e08fda0975a7abfb23814a86a0caf53e482
