[PATCH] D42224: Don't assume a null GV is local for ELF and MachO

This is already a simplification, and should help with avoiding a plt reference when calling an intrinsic with -fno-plt.

With this change we return false for null GVs, so caller only needs to check the new metadata to decide if it should use foo at plt or *foo at got.
