Thank you for the heads up, Kiran! I did not change `-Wrealloc-lhs`, so they should behave the same way. Those that use `-fno-realloc-lhs` may start failing at higher opt-levels, because Flang may stop generating calls to the runtime.  As long as `-fbounds-check` is not supported (https://github.com/orgs/llvm/projects/12?pane=issue&itemId=29048733), I will have to disable them.  I will update the suite after merging this PR.
