Add a regression tester to McPAT. Joel Hestness wrote these tests and Yasuko
Eckert modified them to reflect the new McPAT interface and other changes
the previous patch made.

+Introduction
+============
+
+This regression tester is for the McPAT power model.
+This tester can compile and runs McPAT on the input contained in the
+specified directory, and then compares the output to that of a golden run in
+order to ensure that specific power and area calculations do not change.
+
+Nine tests are included in the initial version of this tester in the directories:
+    $GEM5/ext/mcpat/regression/test-*
+
+In each directory, you will find a regression test input file
+(power_region0.xml) and the golden-run output (region0.out.bak).
+The tester's output file is saved as region0.out, which is then checked against
+region0.out.bak.
+
+
+Options
+=======
+--help, -h      Show a help message and exit
+--build, -b     Build McPAT before running tests
+--cleanup, -c   Clean up the specified regression directory
+--force, -f     Force run regression even if directory isn't set up
+--maketest, -m  Set up the specified test directory
+--verbose, -v   Print verbose output
+
+
+How to Use
+==========
+
+The regression tester must be invoked from the McPAT directory.
+
+% cd $GEM5/ext/mcpat
+
+
+To run all regression tests:
+% ./regression/regression.py ./regression/
+
+
+To run a particular regression test, specify its directory to the tester:
+% ./regression/regression.py ./regression/test-0
+
+Specify the "-v" option to see a diff of the regression output.
