Peter Collingbourne ce2b45bd7d IR: Do not consider available_externally linkage to be linker-weak. ... From the linker's perspective, an available_externally global is equivalent to an external declaration (per isDeclarationForLinker()), so it is incorrect to consider it to be a weak definition. Also clean up some logic in the dead argument elimination pass and clarify its comments to better explain how its behavior depends on linkage, introduce GlobalValue::isStrongDefinitionForLinker() and start using it throughout the optimizers and backend.
