WeakAnyLinkage	Keep one copy of named function when linking (weak)
WeakODRLinkage	Same, but only replaced by something equivalent.
AppendingLinkage	Special purpose, only applies to global arrays.
InternalLinkage	Rename collisions when linking (static functions).
PrivateLinkage	Like Internal, but omit from symbol table.
LinkerPrivateLinkage	Like Private, but linker removes.
LinkerPrivateWeakLinkage	Like LinkerPrivate, but weak.

isWeakForLinker - Whether the definition of this global may be replaced at link time. NB: Using this method outside of the code generators is almost always a mistake: when working at the IR level use mayBeOverridden instead as it knows about ODR semantics.

bool llvm::GlobalValue::use_empty_except_constants ( )

Determine if the usage of this global value is empty except for transitively dead constants.

If the usage is empty (except transitively dead constants), then this global value can be safely deleted since the destructor will delete the dead constants as well.
