[rubygems/rubygems] Avoid allocating empty hashes in Index
Since the hashes have a default proc that returns a (new) empty hash, we
can avoid allocating those empty hashes when we are only doing lookups.
Test from running `bundle update --bundler` against a rails app I have
lying around:
```
==> memprof.after.txt <==
Total allocated: 9.71 MB (68282 objects)
Total retained: 4.87 MB (33791 objects)
==> memprof.before.txt <==
Total allocated: 10.83 MB (100596 objects)
Total retained: 5.02 MB (34721 objects)
```
