This fixes CI for back-deployment testers on platforms that don't have <filesystem> support in the dylib. This is effectively half of https://reviews.llvm.org/D59224. The other half requires fixes in Clang. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@356558 91177308-0d34-0410-b5e6-96231b3b80d8
