tests: Create base classes to encapsulate common test configurations
Most of the test cases currently contain a large amount of duplicated boiler plate code. This changeset introduces a set of classes that encapsulates most of the functionality when setting up a test configuration. The following base classes are introduced: * BaseSystem - Basic system configuration that can be used for both SE and FS simulation. * BaseFSSystem - Basic FS configuration uni-processor and multi-processor configurations. * BaseFSSystemUniprocessor - Basic FS configuration for uni-processor configurations. This is provided as a way to make existing test cases backwards compatible. Architecture specific implementations are provided for ARM, Alpha, and X86.
