  llvm-reduce: Do not delete convergencectrl in operand-bundles (#133858)

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.
