[Inliner] Modernize all of the inliner tests that were using grep. This mostly involved converting from grep to FileCheck and tidying up the IR used. In one case (invoke_test-3.ll) the test had become completely pointless as we use 'resume' rather than 'unwind' now, and even then it did not occur at the end of the line. llvm-svn: 290570

[PM] Turn on the new PM's inliner in addition to the current one for 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

When inlining through an 'nounwind' call, mark inlined calls 'nounwind'. It is important for correct C++ exception handling that nounwind markings do not get lost, so this transformation is actually needed for correctness. llvm-svn: 45218
