If status.vs == OFF, the RVV instruction should raise Illegal
Instruction according to RISC-V V spec. If RVV is not implemented, all
of the RVV instruction need to raise exception.
This moves the clean runner step in our yaml files to be at the
beginning of a job, so that if a runner goes down and is unable to clean
at the end, we can ensure that
subsequent jobs still run as expected.

Due to a 60GB limit on the VMs the gem5 project's GitHub Actions
self-hosted Runners execute within, we cannot run tests which need to
download the gem5 Resource's PARSEC disk image (v1.0.0,
http://resources.gem5.org/resources/x86-parsec?version=1.0.0). This
image, 33GB, is too big and causes our runners to run out of disk space
and fail.
These changes can be reverted when we are able to increase the size of
our VMs.
The x86-parsec gem5 Resource (v1.0.0,
http://resources.gem5.org/resources/x86-parsec?version=1.0.0) is 33GB.
The gem5 GitHub Actions self-hosted runners do not have enough Disk
Space in the VMs they are run to download this. Ergo we skip it.

This argument allows the passing of IDs of resources which should be
skipped for this check.
Note: A current limitation here is you cannot specify the version of a
resource. Passing the ID of a resource to this will skip the downloading
for all versions of that resource.

These tests are disabled due our GitHub Actions self-hosted Runners
having a 60GB of disk space. The PARSEC Disk Image Resource (v1.0.0,
http://resources.gem5.org/resources/x86-parsec?version=1.0.0) is 33GB
and is simply too big to download and unzip for these tests.
These tests can be reenabled when this issue is resolved.

There was another missing file in the configs for the fs tests,
so this should allow the switcheroo tests to pass.

The dailies timed out as they were running the entire directory of tests
due to a wrong variable name being used. In addition, the names of tests
were adjusted to include the matrix type so the artifacts won't
overwrite each other
The configs directory for the fs tests was missing the
checkpoint.py file, causing some of the CI tests to fail.

"tests/gem5/configs/download_check.py" is used by the
"test-resource-downloading" test (defined in
"tests/gem5/gem5-resources/test_download_resources.py" and ran as part
of the "very-long" suite).
Prior to this change "download_check.py" would download each resource,
check it's md5, then at the end of the script remove all the downloaded
resources. This is inefficient on disk space and was causing our
"very-long" suite of tests to require a machines with a lot of disk
space to run.
This change alters 'download_check.py" to remove each resource after the
md5 check. Thus, only one resource is ever downloaded and present at any
given time during the running of this script.

This merges initial support for RVV. Currently, only the simple CPUs are supported.
The decoder stalls for every vsetvl instruction.
In the future, we will implement vsetvl as a control instruction as described in #144
This changeset reorganizes the testing directory within gem5,
removing the bigger config folders, then replacing them with
smaller configs folders within each directory containing only
the scripts necessary for that set of tests. It also changes
the locations of the config scripts used in each set of tests,
and updates the tests accordingly.

This change adds READMEs to each directory within tests/gem5,
with a short description of the test, as well as how to run it.
Change-Id: I574ebcdc837848b52f21e8c0f8856ff09463284b
Since the O3 and Minor CPU models do not support RVV right now as the
implementation stalls the decode until vsetvl instructions are exectued,
this change calls `fatal` if RVV is not explicitly enabled.
It is possible to override this if you explicitly enable RVV in the
config file.

This commit add regs and configs for vector extension
* Add 32 vector arch regs as spec defined and 8 internal regs for
uop-based vector implementation.
* Add default vector configs(VLEN = 256, ELEN = 64). These cannot
be changed yet, since the vector implementation has only be tested
with such configs.
* Add disassamble register name v0~v31 and vtmp0~vtmp7.
* Add CSR registers defined in RISCV Vector Spec v1.0.
* Add vector bitfields.
* Add vector operand_types and operands.
