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.
