b89a54e5c6 new, stricter interface rule: 
in x.(T) x cannot be a nil (uninitialized) interface variable.

remove TODO per discussion.

2d5d4a1b41 reflect bug: NewZeroValue was refusing to create slices. 
as far as I can tell there's no reason not to.

the Nillable test was succeeding because NewZeroValue
returned the nil interface value and the type guard
was letting it through.  the only change in the test is
more detail in the print.

a39bae095a ifaceop was being called with integers 
that came from two different enums.
spilt into ifacecvt and ifaceop depending
on which enum the argument is.

2da5022bcf change representation of interface values. 
this is not a user-visible change.

before, all interface values were

	struct Itype {
		Sigt *type;
		Sigi *inter;
		void *method[n];
	}

	struct Iface {
		void *addr;
		Itype *itype;
	}

the itype is basically a vtable, but it's unnecessary
if the static type is interface{ }.
for interface values with static type empty, the
new representation is

	struct Eface {
		void *addr;
		Sigt *type;
	}

this complicates the code somewhat, but
it reduces the number of Itypes that
have to be computed and cached,
it opens up opportunities to avoid function
calls in a few common cases,
and it will make it possible to lay out
interface{} values at compile time,
which i think i'll need for the new reflection.

47e5152790 fix implicit star for range on *map, *[]. 
do not update lineno from ONAME nodes,
	because they have declaration lineno not use.
show actual name in top-level statement error.

before
runtime.a:7: x.go:5: walkstate: NAME not a top level statement

after
x.go:14: walkstate: runtime.Goexit not a top level statement
