Auto merge of #118352 - Zalathar:llvm-hash, r=onur-ozkan
bootstrap: Memoize the LLVM rebuild hash to avoid very slow `x check` Recently I've encountered a massive regression in the performance of re-running `x check` after making no changes. It used to take around 2 seconds, and now it takes 20-30 seconds. That's quite a hassle when r-a runs it every time I save. After some poking around, what I've found is that each individual call to `generate_smart_stamp_hash` doesn't take a particularly long time (around 0.5 sec), but it gets called dozens of times during `x check`, and that seems to be what's adding up to 20-30 seconds. --- https://rust-lang.zulipchat.com/#narrow/stream/326414-t-infra.2Fbootstrap/topic/Massive.20regression.20in.20no-op.20.60x.20check.60 cc `@onur-ozkan`
