  1. Micro-optimize the WorkerThread::steal loop 

    This lifts up the loop for `Steal::Retry`, so we continue with other
threads before trying again. For most benchmarks, the performance change
is in the noise, but this gives a consistent improvement in most of the
microbenches -- up to 8% faster on `join_microbench::increment_all_max`.
