Avoid query cache sharding code in single-threaded mode

In non-parallel compilers, this is just adding needless overhead at compilation time (since there is only one shard statically anyway). This amounts to roughly ~10 seconds reduction in bootstrap time, with overall neutral (some wins, some losses) performance results.

Parallel compiler performance should be largely unaffected by this PR; sharding is kept there.
