Use string() for convenience for testing where possible, but keep using native() for move tests where we want to check that no allocations are made, constructing a reference fs::path::string_type instead. Use the right value_type in a few places. Make the synop test check for the right types and for the expected preferred separator. Differential Revision: https://reviews.llvm.org/D89537
