[InlineFunction] Don't add lifetime markers for zero-sized allocas. This commit fixes the code which adds lifetime markers in InlineFunction to skip zero-sized allocas instead of asserting on them. rdar://problem/20531155 llvm-svn: 235312

[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
