Fix evaluation of `__has_include_next` during -frewrite-includes. `__has_include_next` requires correct DirectoryLookup for being evaluated correctly. We were using Preprocessor::GetCurDirLookup() but we were calling it after the preprocessor finished its work. And in this case CurDirLookup is always nullptr which makes `__has_include_next` behave as `__has_include`. Fix by storing and using CurDirLookup when preprocessor enters a file, not when we rewrite the includes. rdar://problem/36305026 Reviewers: bkramer Reviewed By: bkramer Subscribers: jkorous-apple, cfe-commits Differential Revision: https://reviews.llvm.org/D45603 llvm-svn: 330041
