Remove obsolete regressions (#5633)
This removes benchmarks for the following reasons: - regress1/arith/arith-int are removed since there are many similar regressions (10 from this set are already enabled) - bitvector cvc benchmarks are removed since their *.smt2 benchmarks are enabled - other benchmarks are removed due to features we do not plan to support - one placeholder benchmark is removed
