Change all the Type::getAsFoo() methods to specializations of Type::getAs().
Several of the existing methods were identical to their respective
specializations, and so have been removed entirely.  Several more 'leaf'
optimizations were introduced.

The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.
