Cherry-pick the LLVM fix for #69225 An additional reproducer was provided in #69225 -- the new testcase here -- which still crashes even after #69241 reverted #67174. Now this pull request updates LLVM with the cherry-picked reversion of its own. This is also going to stable in #69444. I have not tried to reapply #67174 yet -- cc @kraai @shahn

Unrevert "Remove `checked_add` in `Layout::repeat`" This reapplies @kraai's original `libcore::alloc::Layout::repeat` change from rust-lang#67174 which was temporarily reverted in rust-lang#69241. Now that the proper LLVM fix has been cherry-picked, we can unrevert the revert. This change was originally reviewed by @hanna-kruppe on the initial PR. cc @RalfJung

Rerevert "Remove checked_add in Layout::repeat" This change, which originated in #67174 and was reapplied in #69544, seems to have caused a noticeable slowdown in patched/clean incremental builds (see #69710). Revert it for now while we investigate the underlying issue. r? @nnethercote
