Auto merge of #108794 - nnethercote:avoid-unnecessary-hashing, r=cjgillot
Avoid unnecessary hashing I noticed some stable hashing being done in a non-incremental build. It turns out that some of this is necessary to compute the crate hash, but some of it is not. Removing the unnecessary hashing is a perf win. r? `@cjgillot`
