Correctly print an AbstractionPattern with C++ method types

Printing an AbstractionPattern with a CXXMethodType would previously
fail because the code would try to get a Clang type instead. I could
add an if statement but instead, I split off the cases related to C++
method type into a new block, as that seems to follow the pattern in
AbstractionPattern::print().
