nikic 3701e02d32 Use inject-once approach for lexer
Now the lexer is injected only once when creating the parser. Instead of

    $parser = new PHPParser_Parser;
    $parser->parse(new PHPParser_Lexer($code));
    $parser->parse(new PHPParser_Lexer($code2));

you write:

    $parser = new PHPParser_Parser(new PHPParser_Lexer);
    $parser->parse($code);
    $parser->parse($code2);
