[PATCH] D63540: Fix lookup of symbols with the same address range but different binding

Thanks Jan and Omair for the investigation. It does seem like there is some more work to be done on arm/thumb in elf code in lldb, as it seems to me that things are working now more-or-less accidentally.

The good news is that this should not require any fundamental changes since the address class determination happens in ObjectFile::GetAddressClass, we'd probably just need to tweak it's ELF implementation somehow (not fully clear how yet).

But anyway, I do agree that this can be done seperately from the binding prioritization change. As for the change itself, I think we're getting closer, but I am still not convinced by the extra RangeMap::Sort overload. Passing different sort objects to different sort invocations could cause changes done by one Sort call to be undone by further Symtab additions (and/or trigger assertions in the `IsSorted` function). It seems to me that the sort order should be a property of the RangeMap object, set when the object is created, similar to how std::map and friends do this thing...
