#52405 bumps LLVM but it seems to have only been a small patch JuliaLang/llvm-project@julia-15.0.7-9...julia-15.0.7-10.

It caused a 3.5x regression on BaseBenchmarks.SUITE[["array", "index", ("sumelt_boundscheck", "BaseBenchmarks.ArrayBenchmarks.ArrayLF{Int32, 2}")]] which is still present (slightly worse) on master. Long run graph and the Nanosoldier Report.

Feel free to close if not an issue.
