Discard the last uncompleted deferred region in a decl, if one exists. This prevents lines at the end of a function containing only whitespace or closing braces from being marked as uncovered, if they follow a region terminator (return/break/etc). The previous behavior was to heuristically complete deferred regions at the end of a decl. In practice this ended up being too brittle for too little gain. Users would complain that there was no way to reach full code coverage because whitespace at the end of a function would be marked uncovered. rdar://40238228 Differential Revision: https://reviews.llvm.org/D46918 llvm-svn: 333609
