      reflect bug: NewZeroValue was refusing to create slices. · 2d5d4a1b
      Russ Cox authored 
      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.

      change representation of interface values. · 2da5022b
      Russ Cox authored 
      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.
