All the DIS runner scripts as used for the (rejected) RTSS'20 submission

DANGER! There's an inconsistency in the input files used for the
all-pairs tests and those used for the baseline tests.

Baselines: run_all_dis.sh calls run_dis.sh to do all baselines.
All-pairs: Uses old TACLe script (not included here).
Cache allocation 2nd-order effects on SMT friendliness: run_pair_convexity.sh
