Yes, 2 and 3 are worth backporting, I will see how dependent they are on 1.

Indeed, I didn't add a test because there was one already, but the
existing test hasn't the check for clobber generation and store removal.
I prefer to create a new test though, so that the patch and the test
come together, and the test for patch 8 is not encumbered with unrelated
stuff.
By the way, the same could be said about patch 6.
I will create a test for that one as well.

Thanks for the review.
