In the case where no regex was specified (i,e., `regex == None`), the
`_iterable_regex` function returned `None`. For the testlib to work this
function must return an iterable.
Without this patch it is not possible to compare two files without a
specifying a regex.

The
'configs/example/gem5_library_checkpoints/simpoints-se-checkpoint.py'
example would dump the savepoint in the CWD. This is fine when running
as an example, but we also run this script as a test. In this case the
checkpoint litters the repository.
To fix this, an optional 'checkpoint-path' argument is added to this
example which specifies where the checkpoint is to be saved. In the
tests, the checkpoint is saved to 'tests/gem5/resources'. This is our
default location for resources needed/produced by tests and is ignored
by git.

This part of the Kokoro presubmit tests was designed to ensure gem5
still compiled sucessfully with Clang and to the '.fast' variant. ARM
was chosen arbitarily. Now that ALL exists, it makes more sense to use
it for this test.

If the pre-commit could not be installed the compilation would continue
as the exit code from running the pre-commit install script was not
read or processed. This commit adds a check. If the install is
unsuccessful the users is asked whether they want to continue the
compilation or not.
This check can be ignored with the '--ignore-style'. The tests have been
updated to include this flag in all cases we compile gem5 to ensure
tests remain automated and uninterrupted on Kokoro/Jenkins.

The TARGET_ISA variable would let you select one ISA from a list of
possible ISAs. That has now been replaced with USE_ARM_ISA, USE_X86_ISA,
etc, variables which are boolean on or off. That will allow any number
of ISAs to be enabled or disabled individually. Enabling something other
than exactly one of these will probably prevent you from getting a
working gem5 binary, but those problems are being addressed in other,
parallel change series.
I decided to use the USE_ prefix since it was consistent with most other
on/off variables we have in gem5. One noteable exception is the
BUILD_GPU setting which, you could convincingly argue, is a better
prefix than USE_. Another option would be to use CONFIG_, in
anticipation of using a kconfig style config mechanism in gem5.
It seemed premature to start using a CONFIG_ prefix here, and if we
decide to switch to some other prefix like BUILD_, it should be a
purposeful choice and not something somebody just starts using.

Theses improvements are:
1. Renames the test suite to the correct "ResourceDownloaderTestSuite".
This was correctly named MD5FileTestSuite due to a copy-and-paste
error.
2. Adds the `setUpClass` and `tearDownClass` from the Python's unittest
framework. These are used to create the simple "resources.json" file
used for testing, set the "GEM5_RESOURCE_JSON", and delete these when
the test is complete.
3. The tests have been updated to utilize the improvements added in 2.

This commit adds the concept of a "Workload" to the stdlib. Workloads
specify the details needed to run a particular gem5 workload on an
stdlib board. These are specified as part of gem5-resources and loaded
via the `Workload` class though can be specified locally via the
`CustomWorkload` class.
Tests are included in this commit to verify the functionality of these
Workloads.

The `set_se_binary_workload` function was only setting up the binary to
work on one (the first) processor core. This caused an exception to be
thrown when trying to run an SE mode binary on a multicore system.
Tests have been added to ensure this works as intended.
Note: While this implementation fixes the bugs, it is limited. Future
work is needed to allow for multiprogram workloads.

The BaseCPUProcessor is processor containing BaseCPUCores. This gives
gem5 stdlib users a way to create processors containing BaseCPU
SimObjects. While SimpleProcessor does this by-proxy (the user simply
specifies the desires CPUType and ISA and the correct BaseCPU
instantiation is chosen), this new Processor allows a more raw passing
of BaseCPU objects.
The SimpleProcessor now inherrits from this BaseCPUProcessor to avoid
duplcation of functionality. A refactor to achieve this was moving the
setting of the board's memory mode from the SimpleProcessor's
"incorporate_processor" function to the BaseCPUProcessor's then altering
it to determine MemMode based on BaseCPU subclass rather than the
CPUType.
The tests/gem5/configs/simple_binary_run.py test script has been
extended to create an stdlib run with a BaseCPUProcessor instead of the
SimpleProcessor and tests have been included to ensure the
BaseCPUProcessor functions as intended.
Multiple cores comprising of different BaseCPU types has not been tested
and is not officially supported as of this commit.

test_hello_se.py:
Added "take_params_progs" to store avaliable isa and the binary names.
Added two new parameters in function "verify_config" to take verifier
and input arguments for the binary.
simple_binary_run.py:
Added a new unrequired args called "arguments" to take input arguments
for the binary. Its default value is [ ] so the
"arguments = args.arguments" in the "set_se_workload" can run without
inputting any args.arguments.
