This adds support for LLVM to accept metadata that doesn't include a top level lexical block in a function. Specifically LLVM couldn't handle this when there were file changes relating to these blocks. I've updated a few test cases to ensure other functionality (such as inlining) isn't affected by this change, but haven't pervasively updated all the test cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173592 91177308-0d34-0410-b5e6-96231b3b80d8
