    gccrs: collector: Move implementation to header
    
    Move implementation from cc file to header, in order to allow call from
    other headers and prevent linker errors.
    
    gcc/rust/ChangeLog:
    
            * ast/rust-ast-collector.cc (TokenCollector::visit): Move
            implementation from here...
            * ast/rust-ast-collector.h: ... to here.
