Rename clang to clang-cc. Tests and drivers updated, still need to shuffle dirs. llvm-svn: 67602 2009-03-24 10:24:46 +08:00			`// RUN: not clang-cc -fsyntax-only %s`
Fix a nasty corner case that Neil noticed in PR1900, where we would incorrectly apply the multiple include optimization to files with guards like: #if !defined(x) MACRO where MACRO could expand to different things in different contexts.
