Andreas Sandberg 17dbb49294 tests: Update SMT tests to correctly configure CPUs
The 01.hello-2T-smt test case for the O3 CPU didn't correctly setup
the number of threads before creating interrupt controllers, which
confused the constructor in BaseCPU. This changeset adds SMT support
to the test configuration infrastructure.
