revert r133003 and fix the bug properly: the issue was that ## in a token lexer is not a paste operator, it is a normal token. This fixes a conformance issue shown here: http://p99.gforge.inria.fr/c99-conformance/c99-conformance-clang-2.9.html and it defines away the crash from before. llvm-svn: 133005
