[libcxx-commits] [libcxx] [libcxx][test] Add support for LLVM-style split tests (PR #188283)

I haven't thought about this deeply yet, but would it be possible to instead add a builtin command to Lit to achieve the same thing? That would have the benefit of being the same thing that split-file does in the rest of LLVM, and not having to introduce a new test file "type" -- we could just use split-files from within a shtest.
