Auto merge of #109117 - oli-obk:locks, r=michaelwoerister
Avoid a few locks

We can use atomics or datastructures tuned for specific access patterns instead of locks. This may be an improvement for parallel rustc, but it's mostly a cleanup making various datastructures only usable in the way they are used right now (append data, never mutate), instead of having a general purpose lock.
