Add spaceship operator to cp-name-parser.y
While debugging gdb, I saw this:
During symbol reading: unexpected demangled name 'operator<=><std::chrono::_V2::system_clock, std::chrono::duration<long int>, std::chrono::duration<long int> >'
This happens because cp-name-parser.y does not handle the spaceship
operator. This patch implements this.
