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
