Because the handling of the E state for multilevel caches
has changed, stats are affected for any non-ruby config
with caches, even uniprocessor simple CPU.
This patch includes the necessary regression updates to test the new ruby
configuration system. The patch includes support for multiple ruby protocols
and adds the ruby random tester. The patch removes atomic mode test for
ruby since ruby does not support atomic mode acceses. These tests can be
added back in when ruby supports atomic mode for real.

rename : tests/quick/50.memtest/test.py => tests/quick/60.rubytest/test.py
Just one test (40.m5threads-test-atomic) is set up for now.
These tests require that the m5threads SPARC binaries are present
in /dist or in test-progs.
