d6a7cefd1e allow any type at all in sys.unreflect;
accomodate empty type table in 6l.

6f07ec721a new interface error messages
package main
	func main() {
		var i interface { } = 1;
		a := i.(*[]byte);
	}

interface { } is int, not *[]uint8
throw: interface conversion

	package main
	func main() {
		var i interface { };
		a := i.(*[]byte);
	}

interface is nil, not *[]uint8
throw: interface conversion

	package main
	func main() {
		i := sys.unreflect(0, "*bogus");
		a := i.(*[]byte);
	}

interface { } is *bogus, not *[]uint8
throw: interface conversion

1983121bbb 6g interface changes:
* allow conversion between nil interface and any type.
	* mark signatures as DUPOK so that multiple .6 can
	  contain sigt.*[]byte and only one gets used.

c249a8de32 rename various magic names.
sigi and sigt:
	sys·sigi_inter -> sigi·inter
	sys·sigt_int -> sigt·int
	Package·sigt_Type -> sigt·Package.Type

	local type T in file x.go T_x -> T·x
	second one T_x_1 -> T·x·1

	method names M on T  T_M -> T·M

correctly handle local embedded types

init functions are the only place left that use underscores

b4f8e01acb more interface checks:
- pointer to interface cannot have methods
	- record type names for better runtime error
