@artagnon , thanks for the review! I think I've addressed or replied to all the comments. 

I'm trying to keep tests addition and the feature/tests update separated, so rebase is necessary to keep that. In particular, the latest update:

* Rebases to the current trunk
* Adds a test speculating two independent strides (to make sure combined predicate is handled properly)
* Addresses various review comments
* Switches SCEVPredicate expansion to be done on VPlan recipes instead of generating LLVM IR (also part of addressing review, but deserved to be a separate commit)
