@nikic D95849 <https://reviews.llvm.org/D95849> has already changed `llvm/test/` to default to `--allow-unused-prefixes`.  I updated a few directories to be `--allow-unused-prefixes` clean (this uncovered improvement to many tests).

Some `update{,_llc,_analyzer}_test_checks.py` use cases may find `--allow-unused-prefixes=false` mode better, but such use cases still appear to be a minority (e.g. @RKSimon/@pengfei/my/others' fixes to test/CodeGen directories).
