The High-Performance In-order (HPI) CPU timing model is tuned to be
representative of a modern in-order ARMv8-A implementation. The HPI
core and its supporting simulation scripts, namely starter_se.py and
starter_fs.py (under /configs/example/arm/) are part of the ARM
Research Starter Kit on System Modeling. More information can be found

This patch adds some more functionality to the cpu model and the arch to
interface with the vector register file.
This change consists mainly of augmenting ThreadContexts and ExecContexts
with calls to get/set full vectors, underlying microarchitectural elements
or lanes. Those are meant to interface with the vector register file. All
classes that implement this interface also get an appropriate implementation.
This requires implementing the vector register file for the different
models using the VecRegContainer class.
This change set also updates the Result abstraction to contemplate the
possibility of having a vector as result.
The changes also affect how the remote_gdb connection works.
There are some (nasty) side effects, such as the need to define dummy
numPhysVecRegs parameter values for architectures that do not implement
vector extensions.
Nathanael Premillieu's work with an increasing number of fixes and
improvements of mine.

When importing the cores.arm package, we currently throw an exception
if a timing model can't be imported due to a missing dependency (e.g.,
the required CPU model wasn't included in the build). This is
undesirable since it prevents other, working, timing models from being
added to the package. Wrap the import_module call in a try-except
block and skip timing models that have missing dependencies.

Instead of hard-coding timing models in CpuConfig.py, use
introspection to find them in the cores.arm model package.
