arch-power: Fix memory leaks from address translation
While performing address translation using the radix tree
walk mechanism, the objects corresponding to the read and
write requests must be freed properly. These contain data
buffers which if not freed, will keep increasing memory
usage and cause the simulator to get OOM-killed quite
early on low-memory systems.

cpu,stats: Fix incorrect stat names of ThreadStateStats
Previously, ThreadStateStats uses ThreadState::threadId() to
determine the name of the stats. However, in the ThreadState
constructor, ThreadStateStats is initialized before ThreadState
is intialized. As a result, the name of ThreadStateStats has
a wrong ThreadID.
This commit uses ThreadID instead of ThreadState to determine
the name of the stats.
This causes a name collision between ThreadStateStats and
ExecContextStats as both have the name of "thread_[tid]".
Ideally, those stats should be merged to the BaseSimpleCPU.
However, both ThreadStateStats and ExecContextStats have
a stat named numInsts. So, for now, ExecContextStats will
have a name of "exec_context.thread_[tid]", while ThreadStateStats
keeps its name.

scons: Removed -Werror for the gem5 20.1 release
While gem5 compiles on all our supported compilers, removing the -Werror
flag on the stable branch ensures that, as new compilers are released
with stricter warnings, gem5 remains compilable.

tests,misc: Updated TestLib and boot-tests for gzipped imgs
In efforts to reduce storage costs and download times, the images hosted
by us have been gzipped. The TestLib framework has therefore been
extended to decompress gzipped files after download.
The x86-boot-tests are, at present, the only tests which use the gem5
images. These tests have been updated to download the gzipped image.

stating that support for python2 will be dropped in future releases of
gem5.
