There isn't an efficient way to do it.  You'd have to walk the whole  
function body and look at the source ranges that each stmt covers,  
stopping at the smallest one that covers the point of interest.  You  
could do this once and build a location -> stmt mapping of course.   
This would be useful if you do repeated queries (such as having a  
mouse float over code etc).
