[PATCH] D90281: [FileCheck] Report missing prefixes when more than one is provided.

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

@mtrofin I favor a detect-potential-mistake-by-default approach as well. If you want to take the lead here, we can take a busy beavers approach. Add the option (initially true by default), create a spreadsheet with ~1500 failures grouped by test directories, post to llvm-dev and encourage maintainers to fix the issues (I would expect most are user errors, not deliberate --allow-unused-prefixes). After the issues are fixed, make the option false by default.
