most of the inliner test cases. The inliner involves a bunch of interesting code and tends to be where most of the issues I've seen experimenting with the new PM lie. All of these test cases pass, but I'd like to keep some more thorough coverage here so doing a fairly blanket enabling. There are a handful of interesting tests I've not enabled yet because they're focused on the always inliner, or on functionality that doesn't (yet) exist in the inliner. llvm-svn: 290592
