Allow labels with same name that a previous typedef

Labels have a separate namespace, so it is correct this combination,
but the problem is the lexer returns a different token for an
identifier after a typedef for it. For example:

	main()
	{
		typedef int pepe;

	pepe:	return 0;
	}

The easier solution is a hack, where we modify the grammar to
accept an IDEN or a TYPE when creating labels.
