[LLVM-C] Redo unnamed_address attribute bindings

Summary:
The old bindings should have used an enum instead of a boolean.  This
deprecates LLVMHasUnnamedAddr and LLVMSetUnnamedAddr , replacing them
with LLVMGetUnnamedAddress and LLVMSetUnnamedAddress respectively that do.
Though it is unlikely LLVM will gain more supported global value linker
hints, the new API can scale to accommodate this.
