Jordan Rose 127f6eef7e [-E] Emit a rewritten _Pragma on its own line.
1. Teach Lexer that pragma lexers are like macro expansions at EOF.
2. Treat pragmas like #define/#undef when printing.
3. If we just printed a directive, add a newline before any more tokens.
(4. Miscellaneous cleanup in PrintPreprocessedOutput.cpp)
