    Remove note about C++ demangler from Rust documentation
    
    A note about the C++ demangler in the Rust documentation hasn't been
    accurate for a while.  Also, it probably isn't clear to users how this
    related to the next bit of text in the same bullet point.  This patch
    removes the obsolete comment.
