This allows `run_bench.sh` to replace all previous general paired
benchmarking scripts. See `run_everything.sh` for an example of how
to use the new script.
This also fixes two critical bugs present in the old scripts:
1. The cpus_list was incorrectly set for resctrl when running
synchronous pair timing with L2+L3 isolation (i). Each write
to that file replaces the previous contents, and it was previously
written once for each core. This prevented the entire 1st core
from using any L3 cache.
2. The competing task list was indexed improperly in the asynchronous
pair timing script. This caused the competing task to always be
identical to the task being profiled.
These issues combine to imply that in the rejected RTSS'20 paper:
- All Level-C SMT timing data is suspect
- Level-A and -B SMT timing data with L2+L3 isolation (i) is
wildly optimistic
