[LLVMdev] linkage types on global alias

[Anton Korobeynikov]

Hi Nick,

Right. We're reflecting linkage specification from gcc, where alias
can be external, weak or internal (undocumented, but created by c++
frontend). As alias is purely linker stuff, there is no 'linkonce' or
'common' there. Symbol can be global, internal or weak.

> part of the verifier was never updated when new linkage types were added?
No, verifier is correct. I'll update langref.
