PR14566: Debug Info: Removing top level lexical blocks 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. llvm-svn: 173592
