  [CodeGen] Filter out available_externally aliases

The Language Reference says that aliases can have available_externally
linkage if their aliasee is an available_externally global value. Using
this kind of aliases resulted in crashes during code generation, filter
them out (the same that the AsmPrinter also filters out GlobalVariables
in emitSpecialLLVMGlobal(); Functions are discarded in the machine pass
infrastructure).
