All references to interposable symbols can be redirected at runtime to point to a different symbol definition (with the same name). For example, if both dylib A and B define symbol _foo, and we load A before B at runtime, then all references to _foo within dylib B will point to the definition in dylib A. ld64 makes all extern symbols interposable when linking with `-flat_namespace`. TODO 1: Support `-interposable` and `-interposable_list`, which should just be a matter of parsing those CLI flags and setting the `Defined::interposable` bit. TODO 2: Set Reloc::FinalDefinitionInLinkageUnit correctly with this info (we are currently not setting it at all, so we're erring on the conservative side, but we should help the LTO backend generate more optimal code.)
