I'm updating some code to for these API changes, and I'm starting to
think it might be nice to add a little method like this to CXXNewExpr:

const CXXConstructExpr* getConstructExpr() {
  return dyn_cast_or_null<CXXConstructExpr>(getInitializer());
}

It seems to be pretty common that code that was looking into 'new'
exprs mostly wanted to dig out information about the constructor (if
any). What do you think?
