Emit crate disambiguators in save-analysis data

[Xanewok]

Needed for rust-dev-tools/rls-analysis#93.
Blocked by rust-dev-tools/rls-data#11. (For now, this pulls my branch rls-data/crate-source)

This will allow to disambiguate different crates types/versions when indexing resulting save-analysis data (most importantly allow to support bin+lib and different crate versions).

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @nrc (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

Resolved conflict and updated version using rls-data 0.12

@Xanewok Is this PR still [WIP], or is it ready to be merged? 🙂

[Xanewok]

@kennytm it's ready!
@nrc in these cases should I do something like r=nrc with bors?

@nrc this failed on compiling rls (rls-data mismatch).
The rls needs to pull new rls-data 0.12, but with that it needs also the updated rls-analysis (PR pending rust-dev-tools/rls-analysis#106).
I pushed a branch upstream with a patch for rls: https://github.com/rust-lang-nursery/rls/tree/multiple-analysis, but that still has to pull my custom branch - not sure if rustbuild with --frozen will let me do that.

What should we do here to resolve this?

[Xanewok]

Updating rls submodule to rust-45468 branch, so it can compile with these changes.
