Added functionality to call Objective-C class methods
correctly, and added a testcase to check that it works.

The main problem here is that Objective-C class method
selectors are external references stored in a special
data structure in the LLVM IR module for an expression.
I just had to extract them and ensure that the real
class object locations were properly resolved.
