`ninja cxx` now succeeds for me locally.

This fixes link errors when producing a DLL for libc++ with clang-cl.
When building a DLL, most of <filesystem> is annotated as dllexport.
When a class is marked dllexport, all of its inline functions are
emitted into the object file. Those inline functions reference
out-of-line functions that are not available because the filesystem cpp
files are not built on Windows because they haven't been ported yet.
