Subject: [PATCH] Make dependency_formats an FxIndexMap rather than a list of
 tuples

It is treated as a map already. This is using FxIndexMap rather than
UnordMap because the latter doesn't provide an api to pick a single
value iff all values are equal, which each_linked_rlib depends on.

     // get a postorder which ensures that all dependencies of a dylib are loaded before the dylib
