[FileCheck] Use %ProtectFileCheckOutput in allow-unused-prefixes.txt Differential Revision: https://reviews.llvm.org/D90631

[FileCheck] Report missing prefixes when more than one is provided. If more than a prefix is provided - e.g. --check-prefixes=CHECK,FOO - we don't report if (say) FOO is never used. This may lead to a gap in our test coverage. This patch introduces a new option, --allow-unused-prefixes. It currently is set to true, keeping today's behavior. After we explicitly set it in tests where this behavior was actually intentional, we will switch it to false by default. Differential Revision: https://reviews.llvm.org/D90281

[FileCheck] Make --allow-unused-prefixes cl::ZeroOrMore cl::ZeroOrMore allows the option to be specified multiple times, which makes downstream projects possible to specify a default value in lit configuration while some tests can override the value.

[FileCheck] Default --allow-unused-prefixes to false Link: https://lists.llvm.org/pipermail/llvm-dev/2020-October/146162.html "[RFC] FileCheck: (dis)allowing unused prefixes" If a downstream project using lit needs time for transition, add the following to `lit.local.cfg`: ``` from lit.llvm.subst import ToolSubst fc = ToolSubst('FileCheck', unresolved='fatal') config.substitutions.insert(0, (fc.regex, 'FileCheck --allow-unused-prefixes')) ``` Differential Revision: https://reviews.llvm.org/D95849
