Prune no-op statements with a single traverser We put pruning literal statements and pruning empty declarations in the same traverser, as some of the required logic is the same. This pruning of no-ops is always done as one of the first processing steps after parsing, so further processing of the AST is simpler. Since we now prune pure literals before removing no-op cases from the end of switch statements, we also don't need any sort of special handling for switch statements in pruning pure literals.
