The strippable Swift reflection sections contain subtractor relocations
that need to be applied. There are two situations we need to support.

1. Both symbols used in the relocation come from the .o file (for example, one symbol lives in __swift5_fieldmd and the second in __swift5_reflstr).
2. One symbol comes from th .o file and the second from the main binary (for example, __swift5_fieldmd and __swift5_typeref).
