[PATCH] Aliasees no longer have to be GlobalObjects

[Michael Kuperstein]

Thanks Rafael.

So, the problem is that I'm not sure how to construct a test-case for this.
I've ran into it when debugging a crash in InstCombine and having bugpoint itself crash on the module while trying to reduce it. And it looks like bugpoint is also the only thing actually using this interface.

I'll commit it as is, if you have a good idea for how to test this, let me know.
