  llvm-reduce: Do not delete convergencectrl in operand-bundles

The IR verifier will fail if there are any convergent calls without
a convergencectrl bundle, if there are any convergencectrl bundles.

With the current verifier rules, we would need to drop all the instances
of convergencectrl in the function as a set, and strip all the convergence
token intrinsics. As such, I think it would be more appropriate to have a
separate convergence reduction pass.
