Make filesystem::path safe for self assignment
The standard says "If *this and p are the same object, has no effect."
Previously we ended up clearing the path.
* include/bits/fs_path.h (path::operator=(path&&)): Check for self
assignment.
* src/c++17/fs_path.cc (path::operator=(const path&)): Likewise.
* testsuite/27_io/filesystem/path/assign/copy.cc: Test self
assignment.
