This patches does the following:
- Adds 'SimpointResource' which encapsulates Simpoint data and
functionality. It replaces the old 'gem5.util.simpoint.SimPoint'
class. Simpoints can be loaded from gem5-resources using the
`obtain_resource` function.
- Adds 'SimpointDirectoryResource'. This inherits form
'SimpointResource'. While 'SimpointResource' takes raw Simpoint data
via parameters, 'SimpointDirectoryResource' assumes the data exists
in files, in a directory.
- Updates the
"configs/example/gem5_library/checkpoints/simpoints-se-checkpoint.py"
and
"configs/example/gem5_library/checkpoints/simpoints-se-restory.py"
example files to utilize this new Simpoint resource classes.
**Note**: While the old "SimPoint" class
("src/python/gem5/util/simpoint.py") is marked as deprecated, it may be
difficult to utilize given updates to the APIs in the gem5 stdlib Cores
and Simulator modules.
