[PATCH] Add testcases that got lost when tree-ssa was merged

[apinski@marvell.com]

From: Andrew Pinski <apinski@marvell.com>

So I was looking at some older PRs (PR 16016 in this case),
I noticed that some of the testcases were removed when
the tree-ssa branch was merged. This adds them back in.

OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.

Thanks,
Andrew Pinski
