That's what the xunicode package does if I'm not mistaken.

And in addition if you want to deal similarly with legacy TeX  
ligatures such as --, ---, !`, ?`, '', ``, then you need to switch the  
tex-text teckit mapping.

Which would transform your preamble to:

\usepackage{fontspec,xunicode}
\defaultfontfeatures{Mapping=tex-text}
