Done

I moved it to expr.cc . We don't need to cross-compile it so it seems better 
not to put it in impala-ir.cc

The macro name is kind of misleading: one of the use cases is to use the 
handler to throw a custom exception class rather than a boost exception.

So it might even make it easier to gracefully handle boost exceptions if we 
wanted to go down that path.
