tests: add Pannotia to weekly regression

Add the Pannotia benchmarks to the weekly regression suite.  These
applications do a good job of testing the GPU support for irregular
access patterns of various kinds.  All inputs have been sized to use
relatively small graphs to avoid increasing runtime too much.  However,
even with small input sizes Pannotia does run for a while.

Note that the Pannotia benchmarks also use m5ops in them.  Thus, this
commit also adds support into the weekly regression for compiling the
m5ops (for x86, since that is what the GPU model assumes for the CPU).
