1da209140c cpu: Add support for protobuf input for the trace generator 
This patch adds support for reading input traces encoded using
protobuf according to what is done in the CommMonitor.

A follow-up patch adds a Python script that can be used to convert the
previously used ASCII traces to protobuf equivalents. The appropriate
regression input is updated as part of this patch.

9c5ef235cc tests: Add support for skipping tests, skip EIO tests if not enabled 
The EIO tests depend on the EIO support from the "encumbered"
repository, which means that they are not normally built with
gem5. This causes all EIO related tests to fail, which is both
annoying and confusing. This patch addresses this by adding support
for skipping tests if certain conditions (e.g., the presence of a
SimObject) can not be met. It introduces the following Python
functions that can be called from within a test case:

  * skip_test -- Skip a test and optionally print why the test was
                 skipped.

  * has_sim_object -- Test if a SimObject exists.

  * require_sim_object -- Test if a SimObject exists and skip, or
                          optionally fail, the test if not.

Additionally, this patch updates the EIO tests to check for the
presence of EioProcess.

7216681561 config: Reduce DRAM controller regression traffic rate 
This patch changes the traffic generator period such that it does not
completely saturate the DRAM controller and create an ever-growing
backlog in the queued port.

A separate patch updates the stats.

8fe556338d stats: Update stats to reflect use of SimpleDRAM 
This patch bumps the stats to match the use of SimpleDRAM instead of
SimpleMemory in all inorder and O3 regressions, and also all
full-system regressions. A number of performance-related stats change,
and a whole bunch of stats are added for the memory controller.
