[PATCH] D49362: [ThinLTO] Compute constant references

[Eugene Leviant via Phabricator via llvm-commits]

evgeny777 added a comment.

1. Now importing globals list from DICompileUnit in IRMover. This is needed because we may internalise GV in destination module, so it can reach final link.

2. Fixed bug which caused llvm-lto internalising exported symbol with `-thinlto-action=import`

3. Overall approach was reimplemented in much simpler way

4. Added extra tests.
